Monster of Mazinaw Trail Race 2026

Experience the unparalleled beauty of Bon Echo Provincial Park as you take on Canada's shortest ultramarathon, spanning 43 kilometers through some of Ontario’s most scenic terrain. This race is sanctioned by Athletics Ontario and supported by La Sportiva, offering runners a unique opportunity to participate in a trail event that promises both challenge and reward.
The course weaves its way through diverse landscapes, from wide groomed trails to technical single-track paths. The latter will certainly test your skills as they dominate the route with their rocky surfaces, roots, steep descents, and ascents. Be prepared for conditions that can be slippery when wet, requiring a high level of self-reliance.
Due to recent trail damage caused by storms in 2022, specifics about the exact course are still being determined. However, organizers remain optimistic that most sections will be cleared before race day. Participants should expect a generous 8-hour cut-off time, allowing ample opportunity to appreciate the breathtaking scenery without the pressure of strict timing.
Aid stations along the route will provide essential supplies such as water, electrolyte drinks, and various snack options including PB & J, sweet, and salty treats. Runners are encouraged to bring their own hydration systems due to limited access points on back-country trails.
This event is ideal for experienced trail runners looking for a challenging but rewarding experience amidst Ontario’s natural wonders. Wildlife sightings are common, with the chance of spotting rare species like the endangered five-lined skink or more commonly seen creatures such as moose and black bears. Always maintain a safe distance from any wild animals encountered during your run.
