Mantario Marathon

The Mantario Marathon is a challenging, self-supported trail event held annually in Whiteshell, Manitoba, over a two-day period in September. Participants can run, hike, or walk along the rugged Mantario Trail, covering approximately 64 km with an overnight camp at Moosehead Lake. The event emphasizes self-reliance, requiring participants to carry all necessary gear, including food, water, and shelter, as there are no aid stations or markings along the trail.

Known for its demanding terrain, including boreal forests, Canadian Shield, water crossings, and significant elevation changes, the event is open to experienced trail users who are prepared for wilderness camping and navigation. It is a non-organized, free event rooted in trail running's spirit of challenge and camaraderie. Visit the organization's website for the most recent information.
