Course
The half is one full lap of the 13.1-mile loop through meadows, past overlooks and up and over a big granite dome. That exposed granite stretch gets hot, so carry water between aid stations.
Tejas Trails marks the course heavily with arrows, caution tape and distance signs at every split. Aid is cupless, and half runners can leave a drop bag near mile 9 at the 360 Bridge gate.
