​The Next Loop 50K/50M/100K/100M Challenge is a continuous, loop-based ultra designed for runners ready to push beyond the marathon and into true endurance territory.

​​

There will be a 50K & 50 Mile Challenge beginning at 7:00 AM on the Saturday the 18th with a 12 Hour cutoff. At 9:00 PM Saturday the will be a 50 Mile Nighttime Challenge start with a 13 Hour Cutoff. 

At 7:00 AM Saturday Morning, the 18th the 100K & 100 Mile Challenge will start with a 24 Hour cutoff for the 100K and a 32 Hour cutoff for the 100M.​

​​

Runners complete as many 5K loops as needed to reach 50 miles or 100 miles within the 32-hour time limit. There are no resets, no hourly starts—just steady forward progress at your pace. Every loop returns you to a fully stocked aid station, giving you consistent support, fueling, and a chance to reset before heading back out.

​​

The course is designed to be approachable for first-time ultra runners while still challenging enough for experienced athletes chasing longer distances. With no DNF mindset—every loop counts—you control how far you go. There are NO DNF's. ALL LOOPS COUNT!

​

Whether you're stepping up to your first 50 miler or taking on the 100 mile challenge, this is your chance to test limits, manage effort, and go further than you have before.

​

Your Endurance. No Limits. One More Loop.
