Monster of Mazinaw
September 20th 2025
Cloyne, ON
This unique event utilizes some of the backcountry trails at Bon Echo Provincial Park. Runners should expect technical sections and longer distances between aid stations. A large section of the 30k and 60k events take place on back-country trails that are very challenging; even for experienced trail runners. These trails are very rocky, have plenty of roots, and have a number of steep descents and ascents. It will be very slippery if wet. Runners will need to be self-reliant through this section and must be prepared to go 15km without aid. We consider this a “graduate” level trail and it is not suitable for runners without trail experience.
