2026: The Year Nice Was Wiped Out by the Heat

What happened

Ironman France Nice and the 70.3 scheduled for June 28, 2026 were cancelled due to extreme heat, after the heatwave warning was extended. The story comes from the team of a registered athlete: a brutal call, made for safety. The same heat pushed the Versailles 70.3 from July 12 to October 11; one German athlete, already within a few kilometers of the start, went home without racing. In Frankfurt the race went ahead, but with a shortened bike and run.

The circuit returned to Nice in September: the 70.3 World Championship took place in mid-September 2026, still with "leaden heat" on the half marathon, as one finisher described it.

What it means for 2027

• Heat is not a remote risk. From 2023, with a marathon starting under the afternoon sun, to 2026, the theme shows up in every race report: train to run in 28-30 °C.
• A mental Plan B. Even those who didn't race talk about "adaptation" as the keyword of the season: you need a taper week you can shift and a strategy that holds up to a shortened course or an earlier start.
• Flexible logistics. With a race that can be cancelled, go for changeable fares on flights and lodging, and a bike that's easy to get back home.

How to prepare for the heat

10-14 days of heat acclimation, ice and sponge rehearsals on afternoon long sessions, body weight checked before and after workouts, sodium and fluids tested in training. The 24/7 Coach plan builds in these blocks starting the previous summer.
