Equalizer Endurance Run

Equalizer Endurance Run is a timed trail ultra in Des Moines, Iowa, starting on October 31, 2026. Rather than a fixed course distance, you enter by duration: a 6-hour, a 12-hour, or the full 24-hour event, and your result is the mileage you accumulate before the clock runs out.

Timed formats change how you race. There is no finish line to chase, only the decision of when to keep moving and when to stop, which makes pacing and eating the whole discipline. The 6-hour is a reasonable first step for anyone who has already run a marathon; the 12- and 24-hour events call for months of long-run volume and a tested nutrition plan. Practice eating on the move during training, and plan for temperature swings across a full night outdoors.
