Guana 50K and 12K Trail Races

The Guana 50K and 12K Trail Races take place at the Guana Research Reserve in South Ponte Vedra. The event includes multiple race formats: a solo 50K, a 50K team run composed of two 25K legs, and a 12K course.

  • 50K
  • 50K team (2x25K)
  • 12K

The 50K course is a 7.75-mile clockwise loop that begins and ends at the trailhead. The trails are mostly hard pack with several oak tree roots to navigate and are approximately 90% shaded. The 12K start line is positioned further into the trail to create the shorter distance. Time limits are set for each race: 9 hours for the 50K, 7 hours for the 2x25K team, and 3 hours for the 12K.

Packet pickup occurs on race day at the start/finish area. All entrants receive a running hat and finishers in each distance receive finisher shirts; team finishers also receive shirts. A post-race awards ceremony is held at the Reef Restaurant on A1A, St. Augustine.

Entry fees vary by date and race category, with listed amounts for early, mid, and day-of registration. Parking in the reserve is $3.00 per vehicle at the southernmost entrance just north of the Exxon gas station. The event is promoted by JTC Running in association with 1st Place Sports and supports local conservation efforts. Visit the organization's website for the most recent information.
