The Next Loop Endurance Series | Lake Carl Blackwell

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

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