Dunns Ultra Marathon Badasses

Dunns Ultra Marathon Badasses is a trail running event held at Dunns Creek State Park in Pomona Park, Florida. The main loop is approximately 11.75 mile and combines compact grass, forest service roads, sandpine scrub and some sugar sand sections. Each loop has about 300 to 350 feet of elevation gain and loss. The route includes two shallow water crossings with optional foot bridges and finishes each loop with about 1.5 mile on asphalt returning to the runner's village. The course reaches Mt. Maars near the 15k mark, which offers views over the forest.
