Who's going to Red Dirt Ultra?

Free. You can start with nothing.

Free, and always will be. NavRun makes money from race-day planning for runners who want it, never from this. Ultras change constantly, sometimes the morning of. Always confirm with the race director and the official website before you rely on anything here.

The course

Where it goes multi-loop

Two clockwise loops of the Sandstone and Caroline Dormon trails through sand, rocks, mud and water crossings, with long stretches that need steady attention to footing. Daylight fades and fatigue builds over the second loop, so fueling, pacing and forward progress keep the day moving to the finish.

Loose and hard-packed sand, rocks, mud and water crossings.

The race

What this one is

The Red Dirt Ultra is run on the Sandstone and Caroline Dormon trails in Kisatchie National Forest, Louisiana. The trails wind through longleaf pine hills with loose and hard-packed sand, rocks, mud, creek crossings, long climbs and runnable stretches along the Kisatchie Bayou. They are shared with ATV riders and equestrians. Aid stations are staffed by experienced ultrarunners, and vegan options are available at the finish line and the mid-loop aid station.
