The Trident Trail Races

The Trident Trail Races take place July 25–26, 2026 at Jupiter Ridge Natural Area in Jupiter, Florida, near 1800 South US Highway 1. This is the eighth running of the event. The course uses ancient sugar sand dunes within a 271 acre coastal scrub preserve that supports over 200 plant and animal species. The highest natural point on the course is about 44 feet above sea level.

The event offers multiple, looped race formats on soft sand with repeated short climbs and descents. Heat and humidity are emphasized as important factors; heat training is strongly recommended. Medical staff will be on site and aid stations will supply ice, water, fuel and chilled fruit. Certain races require qualifying results from recent long distance or timed efforts.

Distances and formats include:

  • Nooner Half Marathon - 13.2 miles (four 3.3 mile loops)
  • Ciento Dos - 102 miles (31 loops, 36 hour cutoff)
  • Immolation - 80 miles (24 hour elimination format)
  • A Series of Unfortunate 5Ks - 3.3 to 33 miles (up to ten loops)
  • Twilight Trident - 13.2 miles night half marathon

Refund and deferral policy: full refunds minus the registration platform fee available until March 1, 2026; full deferrals available until July 23, 2026. Crew access and crewing details vary by race; Ciento Dos allows crewing near the start area. Visit the organization's website for the most recent information.
