Wausaultra Single, Double, Limitless

WausaUltra in Sylvan Park, Wausau, Wisconsin, offers three formats: Limitless (last-runner-standing), Solo, and Double. All races share a 4.167-mile all-trail loop that threads through woodlands, climbs, and a creek-side descent, with a welcoming home base for tents, aid, bathrooms, and parking between laps. The Limitless format repeats the loop until only one racer remains, creating a backyard-style, competitive atmosphere. Solo and Double let competitors complete 1 or 2 loops (4.167 or 8.334 miles) within a 3-hour window. A kids’ race adds a family-friendly touch to the weekend event.
