Potawatomi

Founded in 2001 at McNaughton Park in Pekin, Illinois, Potawatomi runs ten laps of a 10-mile single-track loop — dirt trail through forest and prairie with creek crossings and rolling hills — totaling 100 miles and roughly 16,000 feet of gain. Concurrent 50-, 150-, and 200-mile distances share the same loop across multiple days. Aid stations sit every 5 miles; a 34-hour cutoff ends the event Sunday at 4 PM. Spring timing in central Illinois brings reliable mud and variable weather.
