About This Race

The Texoma Challenge brings runners to the rolling foothills of North Texas for a versatile endurance event at Waterloo Park in Denison. The race offers seven distance options from 5K to 50K, including a unique rucking division and relay format, making it accessible to runners across the experience spectrum. The course follows a distinctive 6.2-mile loop through varied terrain that showcases the natural character of the Cross Timbers region. Set against the backdrop of Lake Texoma, this event provides a testing ground for both newcomers to trail running and seasoned ultrarunners seeking a manageable challenge. The loop format allows for excellent spectator access and crew support, while the multiple distance options create a festival atmosphere where runners of all abilities share the trails. The relatively flat elevation profile makes this an approachable entry point for runners transitioning from road to trail, though the technical nature of North Texas terrain still demands respect and preparation.

The course consists of a 6.2-mile loop beginning and ending at Waterloo Park, with runners completing multiple laps based on their chosen distance. The terrain is described as 100% paths, suggesting singletrack and natural surface trails through the Cross Timbers ecosystem typical of this region. While elevation data shows minimal gain, North Texas trails often feature rolling terrain with short, punchy climbs and technical sections that can challenge runners despite modest overall elevation changes.
