IRONMAN 70.3 Mont-Tremblant 2027
A 70.3 at Mont-Tremblant in Quebec: a swim in Lac Tremblant, a bike through the region and a single-loop run through the Old Village and along paved trails.
37 weeks to race day: base season
Plenty of runway. This far out, the win is a boring, consistent base rhythm: aerobic volume, strength, technique. The structured block starts closer in; what you do now decides how high it can climb.
Building for this one? 70.3 training plan covers the sessions, the weekly shape and how the block is paced. The R.A.C.E. Framework explains why it is built that way.
Build my complete road.
Commit to the date and the work gets a shape: your countdown starts, the emails arrive in step with your build, and the app anchors a recovery-led block so the final week lands exactly on race day.
One confirmation email, then the road begins. Registering for the race itself stays with the organiser.
“The organiser publishes no elevation figure for this mountain-region bike, so check the route map for climbing. The run is a single loop through the Old Village and along paved trails.”
