Taking place on July 4, 2026, The Limberlost Challenge invites trail runners to explore 10,000 acres of pristine forest, lakes, and wetlands in the heart of Ontario’s wilderness. The event offers multiple technical trail distances—7 km, 14 km, 28 km, 42 km, and 56 km—over terrain dotted with steep inclines, creek crossings, and wetlands rich with beaver dams, challenging both agility and endurance. Runners enjoy a well-marked course, enthusiastic volunteer support, and a hearty post-race meal, all while supporting Trails Youth Initiatives. The event has added sustainability features such as a “No T-Shirt Green Option,” where participants who opt out of receiving a race shirt fund a donation to the Muskoka Conservancy, reinforcing the race’s environmental stewardship goals.
