Treasure Coast Endurance Challenge 2026

The Treasure Coast Endurance Challenge takes place at Jonathan Dickinson State Park in Hobe Sound, Florida, starting on SE Federal Highway. This is a navigation-focused endurance event, not a simple road race. Participants use pre-plotted CalTopo maps to locate checkpoints situated at trail junctions, canals, bays, and wetlands. The event offers a 5K trail run and 4-hour or 8-hour adventure race formats, with distances ranging from 5 km to 38.6 km. The course crosses the park’s trails, waterways, and natural terrain. Racers will trek or trail run, cycle single-track mountain bike paths, travel on dirt and gravel roads with some paved sections, and paddle flat water via kayak or canoe. The 5 km trail run is the most attended choice, but the adventure races are the unique aspect of the series, requiring participants to navigate, change between disciplines, and select their own routes rather than following a marked running path.
