About the race

The course surface is rooty and dirt single-track with rolling hills and about 500 ft of elevation gain per loop. Historic average temperatures for the event period are between 68 and 80 degrees.
Headlamps are required for all events because this is a night run. Participants must carry water using a handheld bottle or hydration vest; this is a no-cup race. Main aid stations are listed at mile 0 and 6.2 and provide hot and cold foods, snacks, water, electrolytes, pickle juice and ice. A water only station is noted near mile 3.7. Drop bags may be placed near the start and finish area and remain the responsibility of the participant.
Ruck rules use body weight to set minimum load: those over 150 pounds carry 30 pounds, those under 150 pounds carry 20 pounds; ruck sacks or vests are allowed. Ruck finishers receive a Texoma Challenge ruck patch. Relay teams consist of one to five people, each running a 10K loop in turn; relay teams receive championship and runner up awards. Running events award 1st through 3rd overall male and female places and all running finishers receive a Texoma Challenge finisher medal. A last place award exists for the 50K running event and the relay.
Parking is limited to the west side of Waterloo Lake Drive and specified nearby baseball fields. Registration is listed as closed. Visit the organization's website for the most recent information.
