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
1 Loop = 5K
2 Loops = 10K
4 Loops = Half Marathon

From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
