Castroville TT Series

Time trials are both a good and a bad thing, something along the lines of your most-hated vegetable: they’re good for you even though they’re often hard to swallow. A little-known, somewhat informal TT series in the small town of Castroville, Texas, is just what the doctor (or coach) ordered if you’re looking for a good way to improve and measure your bike fitness. It's a great way to practice for the State Time Trial Championships, for example, or to test threshold power.

The Castroville TTs are held the second Sunday of each month from March to September, and the dates for 2015 are March 8, April 12, May 10, June 14, July 12, August 9, and September 13. The 20K/40K course, typically very fast, is a relatively flat out-and-back on FM 471 with a nice shoulder. A police officer is in place to assist with oncoming traffic at the turnaround.

From Austin, the drive to Castroville is about 1.5 hours. The first 20K rider starts at 8:01 a.m., and the first 40K rider leaves no earlier than 8:30 a.m. Start times are assigned by category and time of arrival to the gym on race day.  

The event was formerly known as the Iron Haus TT series. Note that the start is in the same location, but the gym’s name has changed to the Fitwell Medina Valley Fitness.

Start/finish location:  
Fitwell Medina Valley Fitness
842 FM 471 N
Castroville, TX 78009

Preregister via Bike Reg or register on race day beginning at 7:15 a.m. at the gym ($5 late fee applies).
