Trystan's Backyard Ultra

Prairie du Chien, United States • 16 Aug 2025

Trystan's Backyard Ultra, held at La Riviere Park in Prairie du Chien, Wisconsin, is a unique endurance running event featuring a challenging 4.167-mile loop course through scenic trails with 200–350 feet of elevation gain. Runners must complete each loop within one hour, with the race continuing until only one runner remains. The course combines grassy fields, dirt singletrack, and gravel paths under a forest canopy, creating a supportive, community-driven atmosphere. Alongside the ultra, a 1-lap fun run/walk offers a no-pressure option for all ages. The event includes aid stations, race-day festivities, custom shirts, and a prize for the last runner standing.
