MammothMarch Illinois 2027
MammothMarch Illinois takes place on May 15, 2027 at Jim Edgar Panther Creek State Fish and Wildlife Area in Chandlerville, Illinois. The site, including the former Panther Creek Conservation Area, totals 16,550 acres. The event uses a single-circuit loop that covers 20 miles through the state area.
The route mainly loops around Drake Lake and Prairie Lake and traverses mature forest land, agricultural land, grassland and rare hill prairie. The course is paved in parts but is mainly unpaved hiking trails, dirt trails, gravel roads and forest floor. Total elevation gain is around 850 ft.
There is no timekeeping; all participants who complete the distance receive a finisher medal and a personalized certificate. Participants who stop before the end receive a certificate stating the mileage they covered. Aid and refreshment stations are available roughly every 5 to 7 miles and provide toilets, water, energy drinks, electrolytes, fruit, cereal or protein bars, and PBJ sandwiches. Complimentary parking is available on site.
Additional notes for participants include a MammothMarch Hiking Pass system for stamps from previous events, merchandise options with some items available for pick up on event day and others available for shipping, and a final route map to be provided about two weeks before the event.
