A look at the Ironman 70.3 Muskoka bike course

Last year, the Ironman 70.3 Muskoka bike course switched from a loop around Lake of Bays, to an out and back route – going though Baysville and turning around just before Dorset.

Yes, this course leaves a sting in the legs. There’s a reason why the half-Ironman race in Muskoka is dubbed “The Beast of the North.” Early into the ride, you hit the punchy climbs of Brunel Road. It is a tough start to any ride, especially a 90K ride that features over 800m of climbing.

Last year, there were several potholes and road work around 15K into the course. However, those issues this year have since been resolved. The pavement throughout the course is smooth and fast.

While the climbs on Brunel are ‘short and punchy,’ the hills on Muskoka Road 117 are gradual and long. With the steady gradients, you should be able to stay on the aerobars without coming up too often.

For the most part, the size of the shoulder is adequate, but beware of sand or sudden cracks in this area of the road. On race day remember to call your passes and be alert to other riders and vehicles.

Happy racing!
