Event details
The Guana 50K and 12K Trail Races take place on Sunday, December 7, 2025, at the Guana Tolomato Matanzas National Estuarine Research Reserve in Ponte Vedra Beach, Florida. Race options listed by the organizer include:
- 50k individual
- 50k team (2x25k)
- 2x25k team
- 12k
Entry fees are tiered: through October 31, November 1 - November 30, and day-of-race prices are provided by the organizer. The organizer notes that fees shown on the Race Roster registration platform include additional server fees and therefore appear higher. The event is sponsored by JTC Running in association with 1st Place Sports. A local estuarine reserve charity is listed as a beneficiary.
Course and logistics
The 50k course is a 7.75-mile clockwise loop that begins and ends at the trail head. The trail is mostly hard pack, contains several oak tree roots to navigate, and is approximately 90% shaded. The 12k start line is moved forward on the trail to create the 12k distance. Time limits are stated as 9 hours for the 50k, 7 hours for the 2x25k, and 3 hours for the 12k.
Packet pickup is on race day only at the start/finish area. All entrants receive a running hat; 50k and 12k finishers receive finisher shirts. Parking inside the reserve is $3.00 per vehicle, using the southernmost entrance just north of the Exxon gas station. Race photos are posted online after the event.
