The Women of Bike Racing
ATC Racing’s Anne Flanagan & Lori Bergeron

Marla Briley, Sammi Runnels, Anne Flanagan, Lori Bergeron
Behind every woman on a bike, there’s a story, and we’d like to share those individual stories with you. How they got started, what it means to be a bike racer, who they are on and off the bike... We’re starting close to home with the women of our own team, ATC Racing. Our hope is that in sharing our personal experiences—the good, the bad, the embarrassing—we open the door for other new women racers.

ATC Racing is made up of seven very strong and very different personalities. We’re an amateur team, and all of us work a job of some kind (or several). Between us, as Lori Bergeron says in her piece below, there’s one obvious unifying characteristic: we love to race our bikes.

Bike racers are short, tall, big as houses, skinny as rails, pretty as a picture, ugly as a post, prissy, butch, quiet, loud. This sport shows you how highly individual a group of people can be. Even age isn’t necessarily a limiter. Anne Flanagan is in her fifties and works part-time as a nurse. Full of energy and wisdom, she’s a beautiful person inside and out, and I think we all wish we could have her looks now, much less 20 years down the road. You’ve got to watch the derogatory grandma comments around her—e.g., “I’m riding like a grandma today”—because she is one. Lori is 30 like me. I have a 10-month-old baby and am by nature very quiet; my typical night is about as exciting as a bingo match. Lori works as a dessert chef (she makes a mean salted caramel) and occasional pedicabber. She goes out, dates, rock climbs, gets new tattoos—a good portion of her barely 5-foot frame is inked.

Can anyone be a bike racer? Probably not. If the idea piques your interest, though, that might be a sign you’d enjoy it. Check out our new nonprofit, the Women’s Racing Foundation of Austin, and read on to learn more about our first two athletes in the spotlight.

From Anne Flanagan
It is about 100 degrees in the middle of August 2012. I am lined up along with about 10 other women and a few 10- to 16-year-old kids to race my bicycle for the first time. We are at the Driveway, a privately owned racetrack that caters to motorsports, but on Thursday evenings from March to October it is all about racing bikes.

Since that day the Driveway has become a weekly ritual, either racing, volunteering, or just spectating. I joined ATC’s women’s racing team, raced some local and out-of-town road races and have generally fallen in love with cycling. This was not supposed to happen to a woman well into her 50s who thought she would be a runner forever. The Town Lake trail was my second home, and the Decker Challenge and the Austin Marathon were my yearly rituals.

Cycling was part of my rehab activity after a minor knee surgery. I found a couple of women in the neighborhood who were training for triathlons, and I rode with them on their training rides. Judy and Doray introduced me to Lime Creek, Liberty Hill, and South MoPac loops. They taught me how to eat and drink on the bike, and how to change a tire. They gave me the confidence to ride on Austin roads by myself when I had to. When their training ramped up for IM Texas, I went looking for a ride that wasn’t necessarily 100 miles long.

I found the Bagel Ride. I know that those guys wanted me to get lost, but I kept coming back every Saturday. I got dropped plenty of times, got pushed up many hills, and got yelled at for not holding my line, and after about 18 months (yes, it took that long) I felt like I could kind of hang with them, sort of. The Violet Crown guys taught me (still learning) how to ride in a group, stay out of the wind, and ride in a pace line. They taught me about wheels and tires, cassettes and cranks, but the great mystery remains: how does Ted keep his bike so clean?

The mentoring in this sport has amazed me; I see it on group rides and at the races.  For the most part people are encouraging and supportive and are willing to share what they know with those new to the sport. The camaraderie among the women is phenomenal. I feel blessed to have found this sport, even at this later stage in life.  I know that my arthritic knees are happier than they were pounding the pavement, and I hope to be out there for years to come. My hope is to be able to encourage other women who are just getting into cycling through ATC’s newly formed Women’s Racing Foundation of Austin.

From Lori Bergeron
I am in my second season of competitive bike racing. At 26, I picked up a bike for the first time since I was a child, and then shortly thereafter found myself at the Driveway lined up with a group of ladies ready to race. I was wearing tri shorts and a wife beater (gasp!). I lasted a short three laps, feeling like I was hyperventilating. I was instantly in love and ready to get strong!

I’ve always liked excitement. The problem is I find joy in a lot of exciting things. Cycling is a sport that requires a lot of time and dedication. It only seemed fitting when I found myself falling in love with crit racing; the short, mind-intensive races are extremely exciting to me and require less endurance.

As a racing team, all the ladies I race with have a strength they bring to the team. Some ladies kill it time trialing and in road races. We all love what we do, and I think that is what is most unique about female racers in Austin. We all have this one thing in common: We love riding our bikes. I even enjoy my interval training on my indoor trainer. (Never thought I’d say that!) But being able to watch and feel myself grow athletically is easily one of my favorite things about competitive cycling.

Racing is one of the coolest hobbies I have ever found myself involved in. Especially at the Driveway crit in Austin. There is so much fun competition and good people, and there is nothing like the adrenaline rush of riding your bike that fast, learning to handle your bike in tricky situations, and hopefully being one of the first through the finish line!

I don’t have a specific goal with cycling or have aspirations of becoming a pro. For me, cycling is about becoming a stronger athlete and person. High-intensity riding teaches me a lot about myself. It is hard to avoid the flow of emotions that come with competition. It has made me more aware of my strengths, my weaknesses, and who I want to become as a friend, an athlete, and a person in general.
Cycling creates an emotional and spiritual outlet through physical activity. It takes you to beautiful places and at a speed you can appreciate what’s around you. I ride to work. I ride out in the country and in the rolling hills of Austin. It’s awesome and there is nothing like it.

Proudest cycling moment to date? Getting my mom on a bike and training for a triathlon at 58! I get excited to get on my bike every day and to see who I will become every day, and also to learn to grow and become stronger physically and mentally through the amazing world of cycling.

Slow and Steady Wins the Race?

by Ben Munguia

I think the story of the tortoise and the hare has always slightly bothered me. Yes, there are great points to take away about patience, persistence, and pacing (that tortoise did have his pace dialed in). BUT, what if that showboating hare had decided to dial it back a tad and not take so many pit stops along the way? I mean all he had to do was take a few less stops and BAM, victory would have been his.

A lot of us can relate to both of these characters. There are the tortoises who click off miles after miles of training, but they always play it safe and never push their limits. They get great benefit from developing their aerobic systems and being able to handle the miles, but there is definitely something missing in their training. On the other hand, you have the hares that can’t wait to hit the track, mash the pedals, and do a few massive sessions in the pool, only to end up sidelined by injury and burnout. It’s a fine line we must walk to get the right mix of slow and steady, and quick and intense.

The most important thing is to make sure you are getting some sort of mix in your training. Adding in a group ride/run or masters swim is a great way to mix things up and add controlled intensity (okay, not always controlledsee ATC World Champs Saturday ride) to your training. If you feel like you have been pushing a little too much, don’t be afraid to slow things down. I’ll go on "family runs" with my wife and dog when I know I need to go easy. It’s a great way to keep me in check, and it’s always nice to have their company. Now that ATC got my brother set up on a new Cannondale bike, I'll be reaching out to him for more fun training options. Make it an opportunity to run with a friend who’s just starting out, or someone you usually don’t get to train with. Finding the best mix and balance for you is crucial to long-term growth, health, and probably overall happiness in your training.

I’m still learning to find the right mix for me. After noting my injury free streak of 2013, I started 2014 at the other end of the spectrum, injured. I was eager to build on 2013, and also looking for ways to become less tortoise-like and more hare-like. The hare in me definitely came out and I ended up sidelined from running for a good two months. Yay for 2014! I plan to learn from these mistakes going forward and will be more patient in my build back to fitness. While most people are racing or getting ready for their first race of the year, I’m channeling my inner tortoise to patiently build my way back to competing. As the ever controversial Brett Sutton once said, "hurry slowly."

Swim Gear

Warmer weather has arrived and finally looks to be staying. Even for the most reluctant seasonal swimmer, the winter hiatus from the water is over: it's time to work on your inner fish.

Unlike fish, however, you'll probably need to stock up on some equipment to get the job done. We asked ATC owner and avid swimmer Missy Ruthven for tips about what we should have on our shopping list.    


GogglesATC has many different styles, brands, lens colors, and prescriptions (yes, prescription goggles at ATC!), with samples to try on in store. Most are of a one-piece construction, but some have different-sized nose bridges in the package to change out for the perfect fit. A few goggle manufacturers, such as TYR Special Ops and Zoggs, now offer polarized lenses. Some swimmers prefer the mask-style "goggle" for open waterATC also has a variety of these, including AquaSphere, Zoggs, and more.

Tips: A good fit is a goggle that sticks to the face (you'll feel a little suction) without the strap. DO NOT rub the inside of the goggles. All new goggles come with anti-fog on or embedded in the lens, and rubbing the lens smears it and/or makes the anti-fog ineffective.

Caps: Though not necessary or preferred for some swimmers, caps are required in triathlon. Silicone caps are the most popular because they don't pull the hair as much and are very durable. ATC also carries thermal caps for the cold water (50s to low 60s). Lycra caps are a good choice for swimmers who don't like as tight of a fit in their cap and mostly just want to keep the hair out of their face. None of the caps keep your hair dry.

Swimsuits: ATC just got a big shipment of new swimsuits in, offering many different styles to choose from: for men, brief, square leg, and jammers; for women, one-piece, two-piece, full back coverage, and one piece with shorts. Brands include TYR, Speedo, AquaSphere, Rocket Science Sports, Sugoi, and Nike. Almost all the suits are made of chlorine-resistant fabric, so they last much longer than the typical Lycra suit.

Wetsuits:  A wetsuit is a must when the water is cold, and it's a marked performance advantage when a race allows them. Look for an in-depth wetsuit article to come soon. Wetsuits are available for rent and purchase at ATC  year-round.


Swim training equipment can have many benefits:
  • Improve swim specific strength
  • Improve body position/technique
  • Add variety to swim workouts
  • Help you get an idea of what if feels like to swim fast

Hand paddles: These are the rigid plastic “hands” athletes use to build swim-specific strength. Using them can also help teach proper technique. Missy says her personal favorite is the Agility Paddle from Finis (check out Brandon Marsh's review), but ATC carries several different options in all sizes.

Tips: Paddle size is dependent on hand size (ideally, the paddle should be a little bigger than your hand) and experience level in swimming. Beginners should get smaller paddles to avoid the risk of hurting their shoulders.

Pull Buoy: These are often paired with the use of hand paddles. A pull buoy is worn between the legs (near the crotch) to elevate the legs and hips, resulting in better body position in the water. Try to copy this position when not using the pull buoy.

Tip: Don’t kick while using the pull buoy. 

Fins: There are basically two kinds of swim fins: traditional “long” fins and the newer, very popular “short” fins. Missy prefers the shorter fin, as she feels the blade allows for a more natural kick. The purpose of fins is to a) keep speed up while doing swim drills,  b) build strength in kick-specific muscles, and c) feel what faster swimming is like.

Tip: You can use a kickboard while kicking (most people do), but Missy prefers not to use the board, instead kicking on her side with her bottom arm extended. She switches sides when she needs to take a breath.


Snorkels:  Many swimmers are using these to work on their technique and body position without the interruption of turning the head to breathe. Finis makes a couple of different models.

Dry Land “Stretch Cords”:  Can’t get to the pool?  The name gives you a good indication of what the cords dothey're stretchy bands with handles that are anchored on something solid in front of you; you bend at the waist and practice your swim technique. They're a surprisingly effective way to build strength.

Water Radios / MP3 Players: Listen to motivating tunes while you swim.

Swimovate:  These watches will calculate distance (by counting your laps; they don't use GPS).  The watch will even tell you what stroke was swum (and the time, distance in each stroke). More elaborate levels of the watch have the ability to upload information to your home computer for analysis.

ATC's full inventory isn't listed online, so check out the swim center at Barton Springs or ATC 360 in person for more products!

For New Women Bike Racers:
Get Started, Get Connected

Bike racing is an intimidating sport. There’s the equipment, the pack riding, the race tactics, the daily mileage. For a beginner starting from scratch, the prospect can be even more daunting. What kind of wheels or tires should you run? What group rides should you try? Where can you register for races? How do category upgrades work? When should you think about joining a team? And then there are the simple questions that you’re almost too embarrassed to ask. What should you wear? How do you pin a number on? What’s a “rookie mark”? 

We need more women racers in the peloton! If you’re interested and looking for a way into the sport, let us help you make the transition. This year ATC Racing has created the Women’s Racing Foundation of Austin, a nonprofit focused on promoting and growing women’s racing in the local community and beyond. Composed of seven competitive riders, our team ranges in age from 22 to 53 and in occupation from bike messengers and chefs to small-business owners and nurses. All of us are relatively new racers, so we know what it’s like to be the new girl. No question is too silly.

The way it works: We’ll pair you up with an individual rider on the team. You can chat via email or phone, meet up for rides and races, or just have that person available to answer questions when needed. We’ll help you get acquainted with other riders and teams, too. (ATC Racing is not taking on new members at this time.)

Email us at to get connected with us and learn more. You can also check us out at our team website,, and on Twitter. Happy riding!

ATC Staff Picks Under $100

Austin Tri-Cyclist employees know their stuff, so we gave them a homework assignment: name their favorite cycling or multisport product under $100 and tell us why they like it. This quickly evolved into a contest to see who could include the most innuendo (“supple” being an important keyword); not all the results of the experiment were included verbatim.

Adam StroobandtATC manager, triathlete, soon-to-be father of two  

Swiftwick socks, seamless running socks that don’t bunch no matter how soggy they get during summer runs, are Adam’s pick. “Swiftwick is a sock that spoils your toes,” he says, adding that he hasn’t had a blister since he switched to using them. Thin and light, Swiftwick socks are a good choice to wear with minimalist running shoes or tight cycling shoes.
ATC logo design, $15.99
Zero Aspire, $12.99

Dustin BrightATC staff, expert bike/motorcycle/car mechanic, mountain biker

A fan of a Maxxis Ikon 2.25 rear tire and a Maxxis Ardent 2.35 front, Dustin says he recommends the combo for mountain biking “because the Ikon is fast rolling and the Ardent is grippy in the corners to keep you from washing out when you’re shredding.” Also, the tires feature thick sidewalls, which  means you won’t have to worry about ride-ending cuts from sharp rocks. Dustin uses tubeless, so he runs them at 24 psi for a more “supple” ride.

Tristan UhlATC staff, pro mountain biker, accomplished all-around cyclist

Tristan, always the overachiever, chose two items. The first was Honey Stinger Organic Energy Chews. “These are hands down without a doubt the best fruit snacks I have ever eaten,” he says,
energy chews in hand. “Jam packed full of juicy fruit juices and essential vitamins and minerals to help you power through the day. Sometimes I even eat them while riding bikes.”

His second, “supple” pick: Vittoria Latex tubes. “When everything is on the line, I roll with Vittoria Latex tubes,” he says. “Because no other tube can match the superior puncture resistance and supple feel of latex.” (Available for auditions. Please provide bottled water and fruit chews. To reach Tristan’s agent, call ATC and ask for Don.)
Chews, $1.95 ea.
Tubes, $17.95 ea.

Brandon SmithATC staff, Cat 2 roadie 

Brandon gave NeoGenis BEETELITE his endorsement, saying that he’s had some of his best results in and out of competition using the popular new supplement. “It’s organic, no side effects, tastes fine, doesn’t require any ‘loading’ or additional supplementation,” he says. “Amazing product.” BEETELITE NEOSHOT is available in original or black cherry.
10-pack, $34
Individual packet, $3.49

Tim CarrATC staff, former pro-level roadie & mountain biker, suspension-fork expert

“I’m a big fan of the Continental hard shell tires,” Tim says, citing fantastic performance, ample traction, and a smooth ride with the protection of a Gatorskin. He says the 25mm are his favorite; wider is better! Gatorskins are super durable for training, including use indoors on the trainer.

Allison AtkinsonATC staff, Pure Austin spin instructor, member of Haute Wheels elite women’s cycling team

Allison’s go-to recovery drink after every ride or gym workout is Hammer Recoverite (chocolate!). “It contains amino acids, vitamins, minerals, and protein to help repair damaged muscle tissue,” she says. “It tastes great and dissolves easily in milk or water with no clumps!” Hammer Recoverite also comes in strawberry, citrus, and vanilla.
6-pack, $19.50

Kimble WestATC staff, roadie, mountain biker
The ATC Zevlin Bar Tape is Kimble’s pick. “Unlike most bar tapes that are coated in some sort of butter or coconut oil, the Zevlin bar tape becomes tacky while riding, not slick like a slip and slide,” he says. According to Kimble, deciding to get an aluminum bar and stem is the right choice for stiffness and crash resistance, but you can afford to go plush with your bar tape.  

Chris WarrenATC staff, runner, mountain biker, newly initiated roadie 

ATC’s “Renaissance man,” Chris likes the custom ATC Camelbak Podium Big Chill water bottle. The summer months are almost here, making hydration accessories a necessity.These bottles are insulated and large capacity, featuring the stylish ATC logo. CamelBak is the official hydration sponsor of team Garmin-Sharp Barracuda, so you’ll be riding like the pros.

Power Meters Explained
Quarq, Powertap, SRM, Garmin, Power2Max, Vector

by Jack Mott

"Do I really need a power meter?" – an often asked question, with a clear answer. No, you do not need a power meter. Norman Stadler became a two-time Kona champ pacing himself by just "going all out." Eddy Merckx managed to win approximately every bike race he ever entered without one, and set an hour record that stood for 28 years. However, when that hour record finally was broken by Chris Boardman, it was done with extensive use of a power meter to guide his training. A power meter is not absolutely necessary for success, but it can be a fun and useful tool.

What is a power meter anyway? How do they work?

SRM Strain Gauge

A power meter is any device that can measure the power you are producing as you ride your bike. This data, recorded for later analysis and/or displayed on a bike computer in real time, can be used to pace your training or race efforts. All power meters work by using strain gauges, placed somewhere in the crankset, rear wheel, or pedal spindles. The harder you push on the pedals, the more deflection you cause in the strain gauges. As they bend, they send a signal to a computer, which tells the computer how much torque is being applied. Combine that torque with the speed that the crank, wheel, or pedal is rotating, and you can compute power. Fortunately, the bike industry has agreed on a standard method, called ANT+, of transmitting power, speed, and heart rate data to bike computers. You can usually use any "head unit" you want with any power meter you want. If you already have a Garmin 500 computer, for instance, you don't have to purchase a new computer if you get a power meter.

What are power meters good for?

    Pacing Workouts
    Bike workouts are often prescribed in terms of zones or power targets. While heart rate can be used to pace longer intervals, short intervals are problematic since heart rate does not change instantaneously. With a power meter, if a coach or training program prescribes "4x5 minutes @ zone 5 or 300 watts" you will know exactly what to do. You will also know whether you hit your training plan goals and can analyze the power file later or send it to your coach.
    Pacing Races
    By doing practice runs, you can figure out exactly how hard you can ride to finish a triathlon bike leg and still have enough gas to run, or how hard to push during a time trial so that you have nothing left at the line. Using a power meter to pace a race can be especially helpful when the route has climbs or a lot of wind. A cyclist's natural reaction to a hill or headwind is to push much, much harder. While you should push a little harder on uphills, using a power meter to pace allows you to make sure you don't burn too many matches. Late in any race with significant hills or headwinds, you'll find yourself passing people who blew themselves up early on. Compared to time trial efforts, for mass start bike racing a power meter is not as useful for pacing, but you may find it beneficial to gauge your effort in breakaway attempts. However, after the race you can often review your data and identify places where you wasted energy, or didn't attack hard enough, etc.
    40k TT pacing, went out a little too hard

    Monitoring Progress
    Once you hit a decent level of fitness, gains start to come rather slowly. Over the course of a year you might expect to only gain 10 or 20 watts of power on the bike. Without a power meter it can be hard to tell if you're making progress. For example, you may do a monthly time trial event and think you're getting slower only because each month it gets a little windier. With a power meter, you can accurately chart your progress over time. You'll also be able to see your best power efforts over various durations, which can guide your training. For example, you may find that your 30-minute power has been improving, but your 15-second sprints are declining.
    Steady 10 minute power progress

    Tracking Training Load
    Power based metrics such as TSS or kilo-joules can give you a more accurate reflection of the overall training load you got out of a ride. Tracking hours or miles can be misleading. A 4 hour ride going super easy gets you as much credit in hours as a 4 hour hammer-fest. 50 flat miles on your TT bike is not the same effort as 50 miles in the west Austin hills on your road bike.  By tracking energy expenditure (kilo-joules) or more advanced metrics like TSS, you can get a more realistic view into your training load. Advanced users can use "Performance Manager Charts" available in WKO+, Training Peaks, and Golden Cheetah to get a glimpse into the long term fitness and short term fatigue

    Evaluating Your Talents
    By testing your best power at short, medium, and long durations, you can put together a profile of your strengths and weaknesses on the bike. This is mostly relevant in bike racing, a sport in which both aerobic talent and sprinting talent play a role. Using a chart developed by Andrew Coggan, you can get an idea of whether you are currently more suited to sprinting or breakaways or are more of an all-rounder. You can also identify weaknesses and address them. See Andy's article on power profiling for more details. Triathletes who plan to experiment with or transition to bike racing can also get an idea of how they may stack up by referring to the chart.
    Field Testing
    One of the most fascinating applications of a power meter is to use it as a poor man's wind tunnel. This isn't easy to do, as finding the proper location can be difficult and the procedure requires patience and care. For those willing to put in the time, however, a power meter can be used to test equipment and position choices out on the road. With a good location and methodology, you can detect small changes in aerodynamic drag, as was demonstrated by Andrew Coggan in his Aerodynamicists Challenge. In short, you need to find a stretch of road where you can do multiple loops without using your brakes and that is relatively low on wind. Velodromes or out-and-back routes with little traffic are good choices. You also need to know the elevation profile of your route. You can then use the Chung method to estimate your coefficient of drag. The aerolab tool in the free power meter software Golden Cheetah lets you do this without a degree in math.
    Sweet Race Reports
    Everyone loves a good race report, and with a power meter you don't have to say "I attacked the peleton with a big surge!"; you'll know exactly how many thousands of watts you attacked with. You can also post annotated charts of the race for extra fun. Most importantly, you can track your latest power records and brag about them on the internet

Calibration vs Zeroing

Zeroing a power meter is a process where you reset the strain gauge reading that counts as zero torque. Almost all power meters allow you to do this manually via the head unit. Since temperature changes can cause the strain gauge data to 'drift', it is a good idea to zero your meter at the start of a ride, and perhaps once or twice during the ride when you come to a stop if temperatures are changing.  Some meters also offer automatic zero features, which will attempt to re-zero when you coast. The Powertap autozero seems to work fairly well in my experience. Others have found the autozero on the crank based meters to be less reliable.  The Power2Max and Stages meters now deal with temperature drift by having a temperature sensor on board, and adjusting automatically. Because they like to make life difficult, many head unit companies call the zeroing process 'calibration' in their menus and documentation. Do not be fooled, you are not really calibrating!

Calibrating a power meter means checking that the torque values are accurate across a wide range of values, not just zero.  Most power meters can be checked by hanging a known mass off of a crank arm. Some power meters also allow you to adjust the calibration.  This is usually a complex process, that some would leave to the manufacturer. But the brave and careful can do it themselves on certain models, such as Quarq and SRM.

Which one should I get?

There are currently three main players in the market, with a few others on the horizon:

    Quarq - Crank Based

    Quarq is currently ATC's best-selling power meter. It is built into the crank, which means you are free to use any wheels you want and still record your power. It is available with many models and sizes of crank, including Shimano, SRAM, and FSA.   Quarq has been around a long time, and they have a reputation for good customer service and reliable operation. The downside with the crank-based system is that it is sometimes harder to swap the crank from one bike to another. However, if your bikes share the same bottom bracket type, this can be a fairly quick change. Quarq setups require that you glue a magnet to your bike near the crank. The latest Quarq models feature less sensitivity to chain ring changes, and some models offer a left/right power balance output. While left/right power is not measured directly, it is believe to be fairly accurate. With some additional tools users can check and adjust the calibration of Quarq's themselves.
    Powertap - Rear Wheel
    This power meter is built into the hub of your rear wheel.. The Powertap is available on many models of wheel, from the basic Mavic Open Pro training wheel to a HED or Zipp race wheel. You can also purchase the hub alone and build it into the wheel of your choice. Now on their third generation of hubs, Powertap also has a reputation for painless, reliable operation and good customer service. Swapping your power meter between bikes is as simple as a wheel change. The downside of a Powertap is that if you want to train and race with power, you either have to train and race on the same rear wheel or get two of them. One solution to this problem is to get a Powertap with a basic training wheel and put a disc cover on it for races. The latest Gen3 Powertaps feature greatly reduced weight, coming in lighter than many regular hubs. They also feature removable electronics, so  you don't have to ship the whole wheel back for service. Powertaps also are able to provide accurate speed data, and semi-accurate cadence data all in one package, which keeps your bike free of wires and sensors. Thanks to a recent price drop, Powertaps are also one of the least expensive options now with hubs starting at $789 and complete wheels for under $900.  While users can check the calibration of their Powertaps themselves, if it needs to be adjusted the electronics must be sent back to the company.
    SRM - Crank Based

    SRM is considered by many to be the best of the best, but you pay for it. Like the Quarq, these power meters are built into the crankset and are available with many models and sizes of crank. SRM has a reputation for being the most reliable and accurate, with examples in the field that continue to operate after many years of service. Installation requires a magnet be attached to your bike, as with the Quarq. SRM's offers their own Powercontrol head units, which are very expensive but allow for fancy features like real calibration. Garmin 500 head units are not able to disable the SRM autozero function, and this can introduce errors in power data, so be sure to pair it with a Garmin 510 or higher.  Special track versions are available which use multiple magnets for better resolution to get accurate sub-5 second peak power values. Another quirk of the SRM is that while battery life is very long, once it dies you have to send the unit back to SRM for a replacement. A big plus in the SRM's favor is that users can re-calibrate the meters themselves if they wish.
    Garmin Vector - Pedal Based

    The Garmin Vector is now available, and offers direct measurement of left/right power balance.  The strain gauges in the Vector are located in the pedal spindle, and electronic pods communicate to each other, and then broadcast combined signal to your head unit.  Installation is not quite as simple as swapping pedals, as accuracy depends on precise torque, and a 'break in' procedure where you do some hard efforts to 'set' the pedals.  Still, for people with multiple bikes with varying bottom bracket standards, the Vector may be the only viable option. These have not been around long enough to say how their durability and accuracy compares with the other power meters here. They are currently only available with Look style pedals.
    Power2Max - Crank Based

    The first generation of P2M meters were found to be a little lacking in stability under varying weather conditions.  P2M has since added temperature compensation to their power meters, and since then the reviews have been excellent. All power meters suffer from potential error due to changes in temperature.  Most combat this by clever arrangement of strain gauges, and manual and automatic zeroing features.   P2M adds active temperature compensation, which could be very useful in certain situations like long uphill segments where you will not get a chance to auto-zero (which requires coasting) for 30+ minutes. P2M also has the most affordable option of all of the crank based power meters with the FSA crankset coming in at $899.  P2M so far has had great support as well, even showing up at Kona to offer free battery replacement and service for anyone worried about the big day.

    Stages - Crank Arm Based
    Stages offers the most affordable option of all, with a crank-arm+power meter starting at $699.  Like the Power2Max, stages uses active temperature compensation.  It may also be the lightest option available, adding only a few grams to your crank arm (though you have to use a metal crank arm). The downside is stages only measures one leg. Since human left/right power balance is inherently variable, this will lead to error that will be difficult to account for.  Was your latest power record of 5 watts real, or just a day when you went a little harder with your left leg?  Was a recent failed interval set really a failure, or was your balance that day a little more to the right?  Early models have had some growing pains but Stages has been quickly addressing them, such as an improved seal on the battery cover. Reports so far are that the company support has been very good.

Where can I buy one?

Power meters are not generally kept in stock at your local bike shop, as wheel and crank preferences are so personal and varied. However Austin Tri-Cyclist is offering 10% off and free installation on all power meters for the next month. Stop by the shop and ask for Adam Stroobandt, and he'll help you select and order your power meter.

How do I get started?

A good place to start is the book Training and Racing with a Power Meter. This book is full of useful information about training and racing for both triathletes and cyclists.

March Bike Events

Enchanted Rock Duathlon

March offers something for everyone, from the recreational rider to the hard-core crit racer. Check out some of the Austin-area events below, or see and for events farther afield.

Driveway Spring Classic, March 8
Holland Racing ushers in another season of crit racing with the 2014 Spring Classic at the Driveway, one of the best venues Austin has on offer. The course, a twisting 1.63 miles built for racecars, is ideal for the fast of leg and stout of heart, attracting beginners and elite cyclists alike. Online registration is closed, but you can still register day of for some categories. (Note: There’s a healthy waiting list for the cat 4/5.)

The Spring Classic kicks off the regular season of Thursday-night Driveway Series races, which are held March 13-October 16. If you miss out on the Spring Classic, pre-register for this Thursday or buy your season pass!

Fayetteville Stage Race, March 15 & 16
Kat Hunter - ATC Racing - Fayetteville TT
Always well organized and fun, the Fayetteville Stage Race is one of the highlights of the year. The three stages—two road races and a 8.9-mile time trial—are based on elapsed time. Triathletes and strong time trialists tend to enjoy this event. Located roughly between Austin and Houston, Fayetteville is about a 1.5-hour drive from either city.  Read our past race reports from 2013, 2012, and 2011.

20th Anniversary Rosedale Ride, March 22
Offering routes of 26, 42, and 62 miles, as well as a children’s fun ride of 2 miles, the popular Rosedale Ride is a charity ride benefiting the Rosedale Foundation, a nonprofit whose mission is to support the children of Rosedale School, AISD’s only school for children with multiple disabilities. The ride starts and ends at Samsung Austin Semiconductor. Online registration is open!

Blue Norther Duathlon, March 9
A flat and fast course, and a long time favorite event of ATC staff and friends. This event in Seguin Texas is 5k run 14 mile bike and another 5k run.  Sign up and have fun!

Enchanted Rock Extreme Duathlon, March 30
2013 Winner Gray Skinner
If you’re not registered for this year’s Erock Du, then you might want to go ahead and mark your calendar for 2015. The race cap has been reached. This is one of the most interesting multisport events in Texas, however, so even if the odds aren’t in your favor, it might be worth it to contact the race director and get on the waiting list.

About a 20-minute drive from Fredericksburg, Enchanted Rock State Natural Area features three pink granite domes that rise high above the surrounding Central Texas landscape. Erock is great place to visit for hiking, climbing, camping, wildlife viewing, backpacking, and, once a year, a really cool duathlon. The race includes a 5-mile run around the park on the Loop Trail, a 16-mile out and back on the farm road just outside the park, and a 1.2-mile run straight up (and up and up) Enchanted Rock herself.
