Event Overview
The Next Loop Endurance Series at Lake Carl Blackwell is a flexible trail running event located in Stillwater, Oklahoma. The event takes place on a 3.1 mile (5K) trail loop through natural terrain. Participants operate on a loop-based structure where a new lap begins every hour. There is no requirement to commit to a specific distance in advance; instead, runners decide loop by loop how far they wish to go.
Course and Format
The course is a clearly marked 5K loop. Runners begin each loop at the top of the hour. After completing a lap, participants can use the remaining time in the hour to rest and refuel at the base area before deciding to start the next loop. Total results are calculated based on the number of completed loops and the combined total time. There are no traditional cutoffs or penalties for stopping early, as every finished loop is recorded toward a final result.
Distances achieved based on finished loops include:
- 5K (1 loop)
- 10K (2 loops)
- Half Marathon (4 loops)
- Marathon (9 loops)
- 50K (10 loops)
Facilities and Support
An aid station is located at the central base area, providing hydration and nutrition at the start and end of every loop. Because of the centralized format, the venue is accessible for crew and spectators to support runners between laps. The event is held at Lake Carl Blackwell Park, providing a natural setting for the duration of the endurance series.
Logistics
The event has a flat entry fee and takes place within a set timeframe from morning until late afternoon. Registration closes the day before the event. The series is organized by EverFurther Events and focuses on a progression-based model for endurance sports. Visit the organization's website for the most recent information.
