This coming June 22 and 23, Mont Tremblant will once again be host to over 5,000 triathletes from around the world who will be competing in two major events: The IRONMAN 70.3 and the 5150 Mont Tremblant Triathlon.

It was in 2012 that Tremblant welcomed its first triathlon events in the IRONMAN series. That first year, more than 5,000 athletes and their supporters acclaimed Tremblant as one of the best venues and destinations of all the IRONMAN events in over 55 countries.

Thanks to our beautiful landscapes, the challenges of the course, access to accommodation and the pedestrian village, not to mention our famous joie de vivre and the warm welcome of Quebecers, Tremblant quickly became one of the most popular destinations of the IRONMAN series. Indeed, from the first year and in all subsequent editions, the event has been sold a few days after the opening of reservations. Not surprisingly, the events held in Tremblant have been named the best swimming, cycling and running course as well as the best atmosphere by participating athletes from around the world.  Tremblant knows how to celebrate!

In 2023, IRONMAN 70.3 Mont-Tremblant won the 2023 Global IRONMAN Athletes’ Choice Awards for Best Swim and Best Run

Did you know?  Titles 70.3 and 5150 are named in reference to the total distance covered in the 2 disciplines: In miles for the 70.3 and in kilometers for the 5150.

New for 2024

Thanks to the Pro Series, IRONMAN 70.3 Mont-Tremblant will welcome close to 100 professional athletes. A record participation! The Pro Series will be broadcast live, around the world, on different platforms. In Canada and the United States, the race will be broadcast on Outside TV.

For the regular athletes, 45 qualifying places per age group will be awarded for the coveted VinFast IRONMAN 70.3 World Championship which will be held on December 14 and 15, 2024 in Taup?, New Zealand.

If you are a spectator, the swimming start is an event not to be missed.  Excitement and joy are in the air… and in the water!  Departures take place gradually by class of athletes, with the professionals leaving first. To see the athletes in action, head to the transition zone where the athletes prepare for the next stage of their challenge. It’s the transition from swimming to cycling then from cycling to running

Athletes are equipped with a chip which records their times for each stage.  Supporters can follow results live on the IRONMAN app.

Very close to the transition zone, you will find the IRONMAN Village.  Don’t miss the offers from local merchants and the official IRONMAN store.  The stalls and tents will be set up as of Friday, June 21.  Additionally, more than 70 shops and restaurants in the pedestrian village will be available to visitors. A few minutes before 11 a.m., the first athletes will cross the finish line and the last one should finish around 4:30 p.m. Enjoy the show directly from the stands installed at Place des Voyageurs.

As you can imagine, such an event requires a small army to ensure planning and execution in complete safety, both for the participants and the thousands of spectators. More than 800 volunteers will be on site during the weekend to support the athletes and inform spectators. Without them, this event could not take place. The Mont-Tremblant region is very proud of its generous and participatory population.  Thank you to each of the volunteers who are there year after year!

We wish everyone a wonderful IRONMAN weekend in Tremblant.  Don’t forget to upload your photos to Facebook and Instagram with the mention #tremblant… and make some noise for our athletes!
