The Next Loop 50K/50M/100K/100M Challenge | Pinnacle Mountain
About
The Next Loop Challenge is a continuous, loop-based ultra built around steady progress and smart endurance. Runners cover repeated 5K circuits on an approachable course, returning each lap to a fully stocked aid station for reliable fueling, support, and a quick reset before heading back out. With 50 mile, 100K, and 100 mile options, the format emphasizes pacing, patience, and the mental rhythm of settling in for the long haul. Its accessible setup makes it especially inviting for athletes moving up into longer ultras, while still offering a meaningful test for experienced runners aiming for bigger goals. The challenge comes less from technical terrain and more from managing effort, staying consistent, and embracing the cumulative demands of loop after loop. The atmosphere is supportive and encouraging, centered on forward motion and the satisfaction of seeing every lap contribute to the overall journey.
