Course
The Nice 70.3 course
The 1.9 km swim is one loop in the Mediterranean from Plage des Ponchettes, in front of the Quai des États-Unis, with transition right on the Promenade des Anglais. The one-loop 90 km bike climbs about 1,227 m, heading inland from the coast through hill villages to the Col de Vence, with an intermediate cut-off at km 36, before a fast return to the sea.

The 21.1 km run is two flat loops along the Promenade des Anglais, with aid stations every 1.8 km and the finish on the same seafront. Nice hosted the 2019 IRONMAN 70.3 World Championship, and the overall cut-off is 8 h 30.

- Race-day conditions
- IRONMAN lists an average water temperature of 24 °C, with readings of 21–26 °C in 2024–2026, and wetsuits are allowed up to and including 24.5 °C, so a non-wetsuit swim is a real possibility. Air temperatures usually run from about 18 °C at the start to 26 °C or more by the run, with strong sun on the Promenade, so heat and hydration planning matter.
What to train for
The bike is the race: build sustained climbing sessions such as 3 x 20 minutes at threshold on a long climb, and finish with long rides that include 1,200 m or more of ascent.
Practise descending confidently on technical roads, because the drop back to the coast rewards smooth cornering.
Prepare for a possible non-wetsuit sea swim with open water sessions without neoprene, and do bricks in the heat so you run the flat Promenade smoothly instead of just surviving it.

Your build to race day
Taper
Tapering for the Nice 70.3
Start the taper ten to fourteen days before race day. Trim the volume in all three sports, keep short race-pace efforts in each, and do one last short brick so running off the bike still feels familiar. The course is hilly, so keep one short hill session in the first taper week to keep the climbs familiar. With the race on September 12, 2027, your taper starts around August 31, 2027.
