Monster of Mazinaw Trail Race 2026
The event takes place at Bon Echo Provincial Park in Cloyne, Ontario on September 19, 2026. It offers multiple trail distances that run on a mix of wide groomed trails and technical, rocky single track. Large sections occur on back-country trails with limited access.
Distances offered:
- 43 km
- 30 km
- 10 km
Course descriptions note extensive rock, roots, and several steep ascents and descents; surfaces can be slippery when wet. Runners should expect stretches of up to 12-17 km without aid and must be self-reliant with adequate water and food carried in a hydration pack. Aid stations provide water, an electrolyte drink, PB&J, and sweet and salty snacks. The event is cup-less so participants must bring a collapsible cup or bottle.
The race is limited to 250 participants and is sanctioned by Athletics Ontario. Registration includes a race tee, race bib, a custom finisher's medal for finishers, and food and drinks at aid stations. Park admission is not included in the race fee. Bon Echo offers tent camping, yurts, and roofed accommodations; campsite reservations can be made starting five months in advance from April 19, 2026.
