Wasatch Front 100 Mile Endurance Run

Wasatch Front 100 Mile Endurance Run is held in Kaysville, Utah, on September 11, 2026, starting at 5:00 AM. The event offers a single 100-mile trail format through the Wasatch Range, one of the long-standing mountain hundreds in the western United States.

This distance in mountain terrain is meant for runners who already have a 50-mile or 100K finish behind them, and it is a natural end-of-summer goal for those building toward a full night-and-day effort. Your preparation should include at least 20 weeks with consistent climbing and descending, back-to-back long runs, power-hiking practice and an overnight session to test lights, layers and eating when you are tired. Pacing conservatively through the first half and keeping fueling on schedule are what carry you through the second night.
