The Next Loop Endurance Series - Lake Carl Blackwell
The event uses a loop format on a clearly marked 3.1 mile trail loop at Lake Carl Blackwell in Stillwater, OK. Runners complete repeated laps around the same course, and each completed lap counts toward the runner's total distance. Laps start at regular one hour intervals, and lap times are recorded so participants have a per-lap and combined result.
The course follows natural terrain and is signed for repeated laps. A centralized base area provides an aid station before each lap, allowing runners to rest, refuel, and receive support between efforts. Final rankings list participants by the number of completed laps and by combined time for those laps. There are no penalties for stopping; completed laps remain part of an official result.
Practical details include a flat entry fee of $100 and the event location at Lake Carl Blackwell, 11000 W Hwy 51, Stillwater, OK 74074. The format maps completed laps to common distance milestones, letting participants choose how far to go during the event.
Target participants range from runners exploring longer distances to experienced athletes testing pacing and decision making in a controlled loop format. Visit the organization's website for the most recent information.
