Dunns Ultra Marathon Badasses - D.U.M.B.

Dunns Ultra Marathon Badasses is a trail running event held on November 7, 2026 at Dunns Creek State Park in Pomona Park, Florida. The event is organized by Sombrero Running and includes multiple distance options with a main 100 mile race. This is presented as the first 100 mile event in the park's history.

All distances except the 8k use an approximately 11.90 mile loop that combines compact grass, forest service roads, open prairie, canopied forest and some sugar sand sections. Each loop has about 300 to 350 ft of elevation gain and loss. The course reaches the top of Mt. Maars around the 15k mark and includes two shallow water crossings with optional footbridges. The final 1.5 miles of each loop return on asphalt to the runner s village.

  • 100 mile

There are two staffed aid stations on course at about 1.5/3.5 miles and 8.5 miles, plus an aid and grilling station at runner s village. Aid offerings list hydration, hot foods, snacks and other items. Pacers are allowed for the 100 mile and 100k after the third loop with waiver requirements; runners 60 or older may have a pacer at any time. Runners registered for 100 mile may drop to 100k after completing at least 100k but are not eligible for awards if they do so. Charity partners include Sombrero Outreach Foundation and Friends of Dunns Creek State Park. A Friday night camping fee of $30 is charged by the state park.
