Event Overview
The Mantario Marathon is a 64 km self-supported stage race taking place in Whiteshell, Manitoba. Established in 1980, this event is held over two days on the Mantario Trail during the last full weekend of September. Participants navigate through boreal forest and the Canadian Shield, encountering a course characterized by numerous water crossings, wet surfaces, and more than 1500 metres of elevation gain and loss.
The event follows a "Fat Ass" format, meaning there are no registration fees, no provided aid stations, and no official race staff. The experience is inclusive of runners, walkers, hikers, and fastpackers of all genders.
Course Details and Distances
The event is split into two equal segments over two days:
- 32 km (Day 1): Starting at the Caddy Lake South Mantario Trailhead and finishing at Moosehead Lake.
- 32 km (Day 2): Starting from Moosehead Lake and finishing at the Big Whiteshell North Mantario Trailhead.
On the second day, the start order is reversed based on the times recorded from the previous day.
Requirements and Logistics
Participants must be entirely self-sufficient, carrying all necessary food, water, clothing, and shelter for the full two-day duration. Overnight camping occurs at Moosehead Lake, which is a wilderness site with no services.
Navigational skills are essential as the route is not specifically marked for the event. The terrain is considered difficult to follow, and participants are expected to use a map, compass, or GPX files to stay on the Mantario Trail. A "pack in, pack out" rule is strictly enforced for all equipment and waste. Visit the organization's website for the most recent information.
