Event Description
What Is The Next Loop?
The Next Loop Endurance Series is a loop-based endurance running event designed for every type of runner — from first-time 10K participants to seasoned marathoners, ultra runners, CrossFit, Hyrox, and tactical athletes.
You’ll run a 3.1-mile (5K) trail loop, starting a new loop every hour on the hour.
After each loop, you decide:
Run another loop
Or stop — no penalties, no DNFs
Every completed loop counts.
⏱️ How Scoring Works
This event uses a simple, transparent scoring system that rewards consistency, pacing, and endurance.
For each loop:
Time starts when the loop begins
Time stops when you cross the finish line
That loop time is officially recorded
Your overall score is calculated by combining the times of every loop you complete.
There are:
❌ No penalties for stopping
❌ No missed-cutoff failures
✅ Only completed loops counted. This allows athletes at every level to compete meaningfully.
👟 Why This Format Works for Everyone
New Runners:
Run your first 5K, 10K, or Half Marathon without pressure
Stop when you’re done — your result still counts
Compare performance with others completing the same number of loops
Marathon & Ultra Runners:
Test pacing, fatigue, and recovery across multiple hours
Analyze loop-by-loop performance
Use results as a benchmark — not just a finish time
Hybrid / Functional Athletes - (CrossFit, Hyrox, Tactical Games)

Evaluate consistency under fatigue
Test endurance without committing to a fixed distance
🌲 Course & Event Environment

Clearly marked course

🏁 How Far Will You Go? Loops Completed/Total Distance
1 Loop = 5K
2 Loops = 10K
4 Loops = Half Marathon

You are never locked into a distance. Each loop is a new decision.
