Course, logistics and safety

The courses run on the trails of Turkey Bend on Lake Travis. The terrain is rolling with moderate elevation changes and a mix of single-track and wider trails. Marathon and half-marathon courses include viewpoints overlooking Lake Travis and fall foliage scenery. The night sections are marked with reflective trail markers and glow sticks, and aid stations will be stocked.

For participants running during dark hours, a headlamp with fresh batteries is required. Organizers also recommend a backup light, reflective clothing or vest, a personal hydration system, and a cell phone for emergencies. Parking is available at the venue. Non-registered spectators and support crews must pay the Turkey Bend park entry fee. In case of severe weather the event may be moved, postponed to the following weekend, or converted to a virtual option; a decision will be made 24 hours before the scheduled start.
