The Next Loop Endurance Series - Lake Carl Blackwell

The Next Loop: Endurance Series, Lake Carl Blackwell

The Next Loop is a loop-based trail endurance event held on a clearly marked 3.1-mile (5K) trail loop at Lake Carl Blackwell Park in Stillwater, OK. The format lets participants decide loop by loop how far to go; each completed lap is counted toward the official result.

Runners begin each loop on the hour and loop times are recorded from that start to when the runner crosses the finish line. Final results rank participants by the number of loops completed and by combined total time. There are no penalties for stopping; completed loops still count toward an official distance.

Support is provided from a centralized base area. An aid station is available before the start of each loop offering hydration and basic nutrition. The central loop layout makes it straightforward for crew, friends, and family to provide assistance between laps.

Distances accumulate by completed loops. Typical equivalences include:

• 1 loop = 5K
• 2 loops = 10K
• 4 loops = Half Marathon
• 9 loops = Marathon
• 10 loops = 50K

Entry is a flat fee of $100. The event is produced by EverFurther Events and emphasizes a loop-by-loop approach to endurance running with hourly rest opportunities and per-loop timing for performance analysis. Visit the organization's website for the most recent information.
