40/50 Mile Challenge – Indian Camp Creek

The 40/50 Mile Challenge is a continuous loop endurance race designed for runners who want to push beyond traditional race formats while benefiting from a fully supported, centralized course.

​Held alongside The Next Loop Endurance Series, this event runs on the same 3.1-mile (5K) loop, but unlike the hourly format, competitors in the 40/50 Mile Challenge run continuously with a strict time cutoff.

​This format offers a true ultra-distance experience—simplified logistics, consistent footing, and constant access to aid and support.
