November 15-16, 2025

Stumble Weekend 2025 consisted of a Middle National Ranking Event (NRE) and
Susquehanna Stumble XXV. The Stumble is a long distance mass start event with a twist: competitors run between most controls in normal sequential order but occasionally enter a “window” where several controls can be visited in ANY order.
