The Devil's Key 2026
The event takes place on August 22, 2026 at Devil's Glen Country Club in Duntroon, Ontario. It is sanctioned by Athletics Ontario and is held mainly on the Bruce Trail with short sections on Blue Blazed side trails.
Course features include the Devil's Glen ski hill climb, crawling through the "keyhole" on the Keyhole Side Trail, running alongside the Mad River, and climbs through Pretty River Valley Provincial Park to the Bruce Trail high point on the longest route. The event donates CA$20 from each registration to the Blue Mountains Bruce Trail Club.
Distances offered
- 66.6 km with close to 6000 feet of cumulative climbing
- 33.3 km with around 2500 feet of climbing
- 16.66 km with about 1200 feet of climbing and a major ascent in the first 5 km
Logistics and support: aid stations are spaced less than 10 km apart and provide electrolyte drinks, salty and sweet snacks, pickles and PB and J. The event is cup-less so participants must bring a collapsible cup or bottle. Each runner receives a skeleton key to carry and show during the race; losing the key ends the race for that participant.
Cut off times and timing: the 66.6 km event has a 12.5 hour cut off and the 33.3 km event has a 12 hour cut off. The organizer notes very steep descents and technical terrain, and advises appropriate preparation.
Partners and supplies: La Sportiva will have a demo shoe fleet and will give away two pairs. THN Labs provides race gels; ingredients listed are maple syrup, tahini, sea salt and rowanberry extract. Visit the organization's website for the most recent information.
