IRONMAN 70.3 Mont-Tremblant.
Race Mont-Tremblant on your terms.
Mont-Tremblant feels like a resort until you remember what you came to do. Lac Tremblant is the beginning; a long bike through the Laurentians follows, and the pedestrian village is where the running legs must still have something to say.

Your day in Mont-Tremblant
What could you race?
I’m Tom, the coach behind Sense Endurance Coaching. Tell me where you are now and I’ll show you what a strong day in Mont-Tremblant could look like.
The course behind your race
The village finish is earned well before you can see it.
Lac Tremblant makes a spectacular start before the bike pulls you into the Laurentians. The pedestrian village at the finish will give you all the encouragement you need. The real work is making sure you arrive with legs that can still respond. The 2027 bike climbs and run turns need the final map.

Set a limit before the first long rise
The closed mountain-resort course carries real elevation change. Pace the climbs by effort rather than chasing speed.
Cap opening effort. Fuel early.
Laurentian resort roads, return pending
Keep nutrition and power steady while the scenery changes
Finish planned nutrition and hold effort through the remaining terrain before the village run.
Stay patient. Finish planned nutrition.
Tremblant village approach, early run
Let the climb out of T2 become comfortable

Only progress once the first half has held together.
Stay tall. Choose the last move late.
What to check in race week
Confirm the beach entry and buoys at Lac Tremblant, the 2027 bike climbs, the half-marathon course and the pedestrian finish. Check local shuttles and vehicle access well before race morning. Don't assign climb targets from an older host description.

Your plan, in race week
Prepare for Mont-Tremblant
Build the legs.
Practise the decisions.
A finish range gives you something to work towards. The preparation is specific to this race: open-water composure, hill-aware power and a comfortable first resort run section are rehearsed without depending on the old course for directions.
I’m Tom. With Sense Endurance Coaching, I’ll build that preparation around your life, follow how you respond and adjust the work as you get closer to Mont-Tremblant.
