The Devil's Key 2026 : Event details
The event takes place at Devil's Glen Country Club, Simcoe County Road 124, Duntroon, ON, Canada, and is sanctioned by Athletics Ontario. The course runs mainly on the Bruce Trail with some short sections on side trails marked with blue blazes. Twenty dollars from each registration supports the Blue Mountains Bruce Trail Club.
Three distances are offered:
- 66.6 km, full course reaching the highest point on the Bruce Trail.
- 33.3 km, mid distance with about 2500 feet of elevation gain.
- 16.66 km, short course with nearly 1200 feet of elevation gain.
The routes include multiple major climbs and technical descents, including the Devil's Glen ski hill climb, running alongside the Mad River, and climbs through Pretty River Valley Provincial Park on the longest course. A "keyhole" section requires participants to literally crawl through or take a longer bypass. Aid stations provide electrolyte drinks, salty and sweet snacks, pickles, peanut butter and jam, and more. Race kits include gels supplied by THN Labs made from maple syrup, tahini, sea salt, and rowanberry extract. La Sportiva will attend with a demo shoe fleet and prize pairs.
Each participant receives a skeleton key that must be shown during the race; losing the key ends the participant's race. Aid stations are spaced under 10 km and the event is cup-less, so runners need a collapsible cup or bottle. Visit the organization's website for the most recent information.
