About This Race
The Texoma Challenge brings together runners of all distances for a multi-format event in the rolling countryside of North Texas. Set in the foothills around Waterloo Park in Denison, this June event offers seven different options ranging from a 5K to a 50K ultramarathon, plus specialty categories including a 10K ruck march and relay divisions. The race's unique 6.2-mile loop system allows spectators and crews to see runners multiple times while providing consistent aid access throughout the longer distances. What sets the Texoma Challenge apart is its inclusive approach to trail running. Whether you're testing trail running for the first time with the 5K or tackling your first ultramarathon with the 50K, the event creates a supportive community atmosphere. The evening start time at 8:30 PM for the longer distances provides cooler running conditions during the Texas summer, though runners should prepare for navigation in reduced visibility. The race serves as both a standalone challenge and a stepping stone for runners building toward longer ultras. With the consistent loop format, pacing becomes crucial for the ultra distances, and the familiar terrain allows runners to focus on fueling and strategy rather than navigation uncertainty.
The course follows a 6.2-mile loop through unique trails beginning and ending at Waterloo Park in Denison, Texas. All distances use portions of this same loop system, with ultra runners completing multiple circuits. The terrain is described as 100% paths, indicating natural trail surfaces throughout the course.
Runners navigate through the foothills of North Texas, though specific elevation details are not available from the current data. The loop design provides consistent access to the start/finish area, making it particularly suitable for crew support and drop bags during the longer ultra distances.
