Red Dirt Ultra

Red Dirt Ultra is a trail running event held on the Sandstone Trail and Caroline Dormon Trail in Kisatchie National Forest, central Louisiana. The course runs through longleaf pine stands and alongside Kisatchie Bayou and features loose and hardpacked sand, stream crossings, climbs and descents, and long runnable sections.

Distances offered

  • 50K (about 33 miles)
  • 100K (about 66 miles)

The course is marked with forest service arrows on trees and contractor flags with reflective tape; flags will be located on the runner's right during the event. Aid stations are placed along the course; some are manned by experienced ultra runners and volunteers, while others are unmanned or water-only. Vegan food options are provided at the finish area and at a mid-loop aid station.

Crew and pacer rules restrict where assistance is allowed. Crews may only access specific aid stations and must follow park speed limits; runners risk disqualification for crew violations. Pacers are not allowed for the 50K; 100K runners may have pacers after completing the first loop, subject to location and conduct rules. Drop bags are permitted at designated locations and must meet size and labeling requirements.

Start/finish parking is at the Day Use parking area on Park Road 395; GPS coordinates for the area are provided in the event information. Camping is available within the national forest on a first-come, first-serve basis. Each finisher receives a medal and top male and female finishers at each distance receive awards.
