Dunes 50K Ultra
Hobe Sound, United States • 25 Apr 2026
DTR Dunes Ultramarathon
The event takes place in Jonathan Dickinson State Park in Hobe Sound, Florida, on a property that covers about 11,000 acres. Courses run across a range of habitats and features inside the park.
Runners pass through pine flatwoods, river swamps and stands of bald cypress. Parts of the route cross an old military base and two named dune areas called Dunes of Heaven and Dunes of Hell. A notable section of the course goes through a sand scrub ecosystem made of rolling white sugar sand; this feature inspired the event name "Dunes."
Distances offered include:
- 50 K Ultramarathon
- Heavy Half Marathon : 13.1 Miles
- Kids Run : 1 Mile
