The Devil's Key 2026
The event takes place on August 22, 2026 at Devil's Glen Country Club in Duntroon, Ontario, Canada. It is sanctioned by Athletics Ontario and will direct 20 USD from each registration to the Blue Mountains Bruce Trail Club.
The course runs mainly on the Bruce Trail with short sections on side trails marked with blue blazes. Key features include the climb to the top of the Devil's Glen ski hill, a literal crawl through the Keyhole on the Keyhole Side Trail, stretches alongside the Mad River, and climbs in Pretty River Valley Provincial Park up to the Bruce Trail highest point for the longest distance.
Distances and notable figures:
- The Beast - 66.6 km with close to 6000 feet of cumulative climbing
- The Half Beast - 33.3 km with about 2500 feet of elevation gain
- The Mini Beast - 16.66 km with close to 1200 feet of gain
Aid stations will be less than 10 km apart and offer electrolyte drinks, salty and sweet snacks, pickles, and pb and j. The event is cupless so participants must carry a collapsible cup or bottle. All participants receive a Skeleton Key that must be shown during the race; losing the key ends the race. Partners include La Sportiva with a demo shoe fleet and two pairs to give away, and THN Labs supplying gels made from maple syrup, tahini, sea salt, and rowanberry extract.
