Course and logistics

Courses run on the trails of Turkey Bend on Lake Travis and feature rolling terrain with moderate elevation changes, a mix of single-track and wider trails, and viewpoints overlooking Lake Travis and fall foliage. Routes are well marked and use reflective trail markers and glow sticks for dark sections. Night running safety items are required or recommended: a headlamp with fresh batteries (required), a backup light source (recommended), reflective clothing or vest, a personal hydration system, and a cell phone for emergency communications.

Packet pickup is provided at Turkey Bend Recreation Area. Parking is available at the venue. Non-registered spectators and support crews must pay the park entry fee; spectator passes can be purchased through the race store. In severe weather the event may move, postpone to the following weekend, or convert to a virtual option; a decision will be made 24 hours before the scheduled date.
