About the race
The Rodeo Trail Run of Austin is a multi-day trail running event held in Spicewood, Texas (640 CR 412). It features set-distance races and loop-based endurance formats on Hill Country terrain with rocky, uneven sections and short steep climbs.
Distances and formats include:
- 13.1 miles Half Marathon on trail
- 28 miles Marathon Ultra on trail
- 4.167 miles Backyard Ultra loop (hourly laps)
- 4.167 miles loops for the 8-Hour Timed Run
- Backyard Duos relay with strict alternation
The Half Marathon and Marathon Ultra run fully on trail, include stocked aid stations, finisher recognition, and a custom participant shirt. Half Marathon registrants receive a 12-week trail training plan. The 8-Hour Timed Run uses the same loop at Grelle Recreation Area; results count only completed loops and a finisher buckle is awarded for completing three or more loops. There is no participant cap for the 8-hour format.
The Backyard Ultra follows official backyard rules: each loop starts one hour after the previous, runners must start at the bell, complete the loop within the hour to continue, and are eliminated if they fail a loop. The Backyard Duos division requires strict alternation between two teammates, a single shared timing chip, and a timed chip exchange in the transition chute each hour; failure to complete the exchange or meet the cutoff results in a DNF.
Field sizes are capped. Entry fees vary by event. Visit the organization's website for the most recent information.
