Course and logistics
The 50K uses a 7.75-mile clockwise loop that begins and ends at the trailhead. The surface is mostly hard-pack trail with several oak tree roots; the course is described as approximately 90% shaded. The 12K start line is moved forward on the trail to create the shorter distance. Time limits are: 9 hours for the 50K, 7 hours for the 2x25K format, and 3 hours for the 12K. Packet pickup is race-day only at the start/finish area. Parking inside the reserve is $3.00 per vehicle; use the southernmost entrance just north of the Exxon station.
