MammothMarch Wisconsin 2026

MammothMarch Wisconsin guides participants through the Northern Kettle Moraine State Forest, located under an hour north of Milwaukee. The event is based at Long Lake Recreation Area in Cascade, offering a demanding summer trail challenge. The format is straightforward: select either a 20-mile option with an 8-hour time limit or a 30-mile option with a 12-hour limit. Participants begin early and must complete the designated loop within the allotted time. This is a hiking event, not a road race, with distances emphasizing completion over rapid times for the majority of participants. The courses consist of single-circuit loops crossing a 30,000-acre forest with rolling hills, lakes, and wooded trails. The location is part of the Ice Age Trail, aligning with the MammothMarch concept of a full day spent hiking rather than a brief park walk. The Wisconsin event has sold out consecutively for three years, indicating its appeal to a diverse group including nature enthusiasts, seasoned hikers, individuals seeking a challenging objective for the first time, and returning MammothMarch participants drawn to the collective effort and the achievement of completing the course.
