Ontario’s only IRONMAN 70.3, this race takes place in a region adjacent to the majestic Great Lakes—a pristine forest getaway in Canada’s cottage country.

Once again, the 2023 IRONMAN 70.3 Muskoka will be at the gorgeous Canada Summit Centre in Historic Downtown Huntsville. The beautiful Canada Summit Centre was renovated and expanded for the 2010 G8 Summit.

The course features a 1.2-mile, one-loop swim in the scenic Fairy Lake. The swim start is just 500m from the transition zone. The 56-mile bike course circles Lake of Bays, passing through the small communities of Dwight, Dorset, and Baysville. The 13.1-mile run will take you through Historic Downtown Huntsville and finishing at the gorgeous Canada Summit Centre.
