Your Endurance. Your Terms.
The Next Loop Endurance Series is designed for athletes who want to explore what they’re capable of — without pressure, intimidation, or predefined limits.
Whether you’re building toward your first 10K, curious how far you're capable of, working to improve your recovery, or how fast you can go, The Next Loop meets you where you are and lets you decide what comes next.
Who is The Next Loop Endurance Series For?
The Next Loop Endurance Series meets athletes wherever they are in their endurance journey.
New Runners
If you’re building confidence or working toward your first 10K, Next Loop gives you structure, support, and a low-pressure way to test yourself.
Experienced Runners
Training for a marathon or half? Use multiple loops to dial in pacing, nutrition, and mental resilience in a controlled environment.
Ultra Curious
Ready to go long? Stack loops, push limits, and stop on your terms. Every distance is earned — and honored.
No pressure. No limits. Just forward progress.
Progression, Not Elimination
Traditional endurance events force athletes to commit to a distance before the race begins.
The Next Loop Endurance Series is different.
-
Athletes start together, complete one 5K loop at a time, and choose whether to continue.
-
Every completed loop counts. When you decide you’re done, your effort is honored — no missed cutoffs, no failure.
-
This format encourages athletes to return again and again, building endurance through experience, not pressure.
