Aid stations are spaced less than 10 km apart and provide electrolyte drinks, salty and sweet snacks, pickles, and peanut butter and jam. The event is cup-less so participants must carry a collapsible cup or bottle. Each registration donates 20 CAD to the Blue Mountains Bruce Trail Club. The race is sanctioned by Athletics Ontario. Race kits include a bib, sticker, shirt, a Skeleton Key that must be carried and shown during the race, a finisher medal, and race photos. THN Labs supplies gels in kits and at aid stations.
