Course, logistics and awards

The 50K uses a 7.75-mile clockwise loop that begins and ends at the trailhead. The trail is mostly hard-packed with several oak tree roots to navigate and is about 90% shaded. The 12K start line is moved forward on the trail to create the 12K distance. Time limits are: 9 hours for the 50K, 7 hours for the 2x25K format, and 3 hours for the 12K.

Packet pickup is on race day only at the start/finish area. All entrants receive a running hat; finishers in each race receive finisher shirts. A post-race awards ceremony will be held at the Reef Restaurant on A1A (4100 Coastal Hwy St, Augustine, FL 32084). Parking inside the reserve is $3.00 per vehicle; use the southernmost entrance just north of the Exxon gas station. Race photos are posted online after the event. No refunds, deferrals, or transfers are offered. Visit the organization's website for the most recent information.
