Rainbow Trail Run

Rainbow Trail Run is a scenic trail-running event held in Alliston, Ontario, Canada, offering runners a welcoming off-road race experience at Earl Rowe Provincial Park in Simcoe County. Centered on a roughly 12-kilometre loop through the park, the event blends double-track trail, grassy sections, dirt paths, bridge crossings, and a modest climb to the lookout, creating a course that feels approachable for first-time trail runners while still giving more experienced participants the option to take on longer ultra-style distances. With race options ranging from shorter loop formats to multi-loop endurance events, the Rainbow Trail Run has developed into a community-focused summer trail race that emphasizes scenery, inclusiveness, and fun as much as competition. The event’s location in a provincial park, along with its relaxed atmosphere and broad distance offerings, gives it a distinctly outdoorsy, cottage-country feel compared with a traditional road race.
