Wausaultra Single, Double, Limitless

The WausaUltra event in Wausau, Wisconsin, offers three race formats: Limitless, Double, and Solo, all held on a scenic 4.167-mile mostly trail loop through Sylvan Park. The Limitless race is a "last runner standing" challenge starting Friday, where participants run one loop every hour until only one remains or until midnight Sunday. The Solo and Double races, held Saturday, allow runners to complete one or two loops within three hours, catering to both competitive and recreational trail runners.

The course features hilly terrain, forest trails, and beautiful views, with a central home base providing aid and facilities. A kids' race under half a mile is also included. Visit the organization's website for the most recent information.
