3 Chaparrals Endurance Trail Run

3 Chaparrals 3/6 Hour Endurance Trail Run takes place in Palo Duro Canyon State Park, Canyon, Texas. The inaugural fixed-time event offers 3-hour and 6-hour options, including a 6-hour relay. Runners cover a 4-mile Kiowa/Comanche Loop on rugged trail terrain, recording the greatest distance completed within their duration; only full loops count.

The course can be technical in places, with a single aid station at the Start/Finish where participants may set up canopies and must bring a cupless system. There are lap cutoffs and an absolute finish window to complete laps. Registrants receive a discount coupon for the Palo Duro Trail Run.
