Ironman Muskoka

We've partnered with the Canadian Breast Cancer Foundation to bring Canada's first ever Iron Girl event! Join us at Nelles Beach Park in Grimsby, Ontario – just an hour away from Toronto and Buffalo – for a 500m shallow and safe swim – 20km flat and friendly bike – and a 5km spectator lined run course. It will be a picture perfect course starting in Lake Ontario, touring Niagara's farmland and finishing on the Waterfront Trail!
