2025 Mountain Bike Events & Races in Ontario

Ontario is established as a go-to destination for great mountain bike events and races. That’s no surprise given the province’s sheer variety of terrain: From ski hills that transform into epic cross-country singletrack trails to long slabs of Precambrian bedrock and rooty technical rides, Ontario mountain biking is world class. Add to that some downhill, cross-country and enduro, and you can certainly find something to challenge your skills, regardless of your ability level.

More and more mountain bike opportunities are emerging as dedicated trail-builders and community groups come together to dream up new rides. This has led to a fiesta of races, festivals and events—all listed here. This is your guide to the year’s best mountain bike races and events in Ontario.
