The Texas Time Trials is an ultra marathon endurance cycling event held on a 26.3 mile loop punctuated by rolling hills around the Brazos River. This long standing event offers 6, 12, and 24-hour time based races where solo riders and relay teams complete as many laps as possible during their respective duration. Additionally the Texas Time Trials offers 1-lap and 500-mile (19 lap) fixed distance races. Please see the 2020 Race Bible for more information. 2021’s race bible will be updated closer to the event. The six-hour event will be the WUCA North American championship race for 2021.
