MammothMarch Wisconsin 2027

MammothMarch Wisconsin is a two-day hiking event held June 26 and June 27, 2027, at the Northern Kettle Moraine State Forest with start and finish at Long Lake Recreation Area in Cascade, WI. The event offers single-circuit routes that showcase the forest's rolling hills, lakes, and wooded trails across the park's roughly 30,000 acres.

Distances

  • 20 miles single-circuit loop, total elevation gain around 900 ft.
  • 30 miles single-circuit loop, total elevation gain around 1,500 ft.

Terrain includes paved and unpaved hiking trails, dirt trails, gravel roads, and forest floor. Aid and refreshment stations are positioned approximately every 5 to 7 miles and provide toilets, food, drinks, and a variety of snacks; these supplies are included with registration. Parking is complimentary on site.

The event does not use official timekeeping; all participants who complete their chosen distance receive a finisher medal and a personalized certificate. Participants who stop early receive a certificate noting the mileage covered. A MammothMarch Hiking Pass system is used for participant stamps; returning participants are asked to bring previous passes to collect 2027 stamps. Final route maps will be published around two weeks before the event. Merchandise is available through the event store and the official online shop; items ordered through the official shop are shipped, while items added during registration are available for pick up on event day.
