About this race

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)

  • Measure recovery between efforts
  • Evaluate consistency under fatigue
  • Test endurance without committing to a fixed distance
     

🌲 Course & Event Environment

  • Scenic trail-based 5K loop
  • Clearly marked course
  • Start/finish located at a central base area
  • Aid station available each hour
  • Family- and crew-friendly atmosphere

 
🏁 How Far Will You Go? Loops Completed/Total Distance

  • 1 Loop = 5K
  • 2 Loops = 10K
  • 4 Loops = Half Marathon
  • 9 Loops = Marathon
  • 10 Loops = 50K
  • You are never locked into a distance. Each loop is a new decision.

🎯 Who Should Register?
✔ Runners of all levels
✔ Athletes training for longer events
✔ Anyone curious how far they can go — one loop at a time
✔ Anyone who wants an endurance challenge without failure pressure

 
🧠 The Philosophy
This isn’t about speed alone. It’s about discipline, recovery, decision-making, and endurance.

Run the loop. Recover. Decide. Repeat.
