The bike events during the Texas Trail Roundup are being hosted by the Whatever of Texas Sporting Club. There will be 13km, 25km and 50km routes on Saturday and Sunday. The start window is from 8:00 AM to 11:00 AM. Both will be along the Mission Trail. For more information, visit the AVA web site.
If you did not bring a bike with you, there are many rental options nearby, from the by-the-hour B-Cycle to more traditional rentals through bike shops.
