Event Description

The spring edition of the DTR Endurance Challenge covers distance for everyone: 5k, 7 Miler, 13.1 Half-Marathon & 50k Ultra Marathon with complete Aid Station support and a great experienced team of volunteers and staff. 

We strongly believe that small seeds grow into mighty trees, hence why we have these 4 distances in our race. Throughout the years we have seen many 5K runners get inspired by 50K finishers. The inspiration from the community of runners involved in this event is contagious. So come get the trail bug on April 28th, 2017.

Join us and experience scenic overlooks, creek crossings, and wildlife in 13 natural communities, including sand pine scrub, pine flat woods, mangroves, and river swamps turning the race into a complete natural adventure. 

Most of the course runs on beautiful single track trails winding throughout this wild and scenic park,  you’ll encounter the famous Dunes of Heaven (13.1, 50K) and Dunes of Hell (50K).
