3 Chaparrals 3/6 Hour Endurance Trail Run
The event is a fixed-time trail run held at Palo Duro Canyon State Park on March 28, 2026. Participants run repeated loops on a four mile Kiowa/Comanche Loop that begins at the Mack Dick Pavilion. The course is a trail route with portions that can be technical. Only fully completed loops count toward an entrant's distance, and there is an absolute cutoff shortly before each race finishes after which no new laps may be started.
Event options:
- 6 Hour individual
- 6 Hour 3 person relay
- 3 Hour individual
The 6 Hour relay is for teams of two to three runners who rotate on the same four mile loop. Exchanges must occur in a designated exchange zone and require a timing chip pass. Each team member must complete at least one loop. The team with the most completed laps wins; if laps are tied the faster total time decides. Teams may set up a base camp or tent within the exchange zone to support food, hydration, rest, and other aid needs.
There is one neutral aid station at the start/finish area. It will offer water, Hyperlyte liquid performance drink mix, cola, ginger ale, pickle juice, gels, and a selection of sweet and salty snacks. This is a cupless race; runners must provide their own bottle, bladder, or cup.
Packet pick-up occurs the two days before the race at listed locations. Awards are planned for overall and masters in individual events, and top categories in the relay. Age-group details will be determined based on entries. Visit the organization's website for the most recent information.
