Quebec’s Mont-Tremblant delivered two different lessons in dominance. Aurélia Boulanger won the women’s race in commanding fashion, and Ari Klau overturned a huge deficit from the swim to take his first professional victory. The race took place on 21 June 2026 and was effectively the last chance to qualify for the IRONMAN 70.3 World Championship in Nice, which explains a start list made up almost entirely of North American athletes.
Boulanger: a lead of more than five minutes
French athlete Aurélia Boulanger left her rivals no illusions. She came out of the water with a real deficit, nearly four minutes down on the leader, but by the 33 km mark on the bike she had moved into the lead and entered the second transition with an advantage of more than a minute. On the run she simply turned the screw: at the halfway point her lead had grown past four minutes, and she crossed the line more than five minutes clear. At half distance that is not a margin, it is a chasm. It was Boulanger’s fourth half-distance win, and the biggest of her career so far.
Women’s podium: 1. Aurélia Boulanger (France), 4:08:34; 2. Lydia Russell (Great Britain), +5:01; 3. Lisa Becharas (USA), +8:42.
Klau: from 24th after the swim to the top of the podium
The men’s race followed a classic “the bike and run save the day” script. Joshua Berles won the swim in 23:08, and Ari Klau came out in 24th place, nearly three minutes down on the front of the race. On the bike the American began cutting into the gap: by the 33 km mark he had moved up to eighth, within two minutes of the lead, and he reached the second transition in third place, just 15 seconds behind Berles.
Klau did not wait around on the run. He pulled clear almost immediately, held a two minute lead by halfway, and carried it to the finish. The fastest half marathon of the day, 1:08:47, gave him victory in 3:41:32, his first professional win, a month after finishing second at IRONMAN 70.3 Chattanooga.
Men’s podium: 1. Ari Klau (USA), 3:41:32; 2. Blake Harris (USA), +2:26; 3. Luke Jones (USA), +4:00.
The lesson from this race
Klau’s win is a good illustration of a rule every age grouper knows: nothing is decided in triathlon after the swim. Three minutes down after the first discipline sounds like a verdict, but there is plenty of time to make it up over 90 km of bike and 21 km of run, provided the engine is there for the second and third parts.
Boulanger showed the other side of the same coin: when an athlete is equally strong across all three disciplines, a race can turn into a solo ride to victory.
