IRONMAN France Nice is a full-distance triathlon with a split personality. The swim and the run belong to the beach — the Baie des Anges and the Promenade des Anglais, flat and Mediterranean and beautiful. The bike belongs to the mountains — 180 kilometres into the Alpes-Maritimes hinterland, where the Côte d'Azur's gentle coastline gives way abruptly to limestone gorges and serious cols.
That contrast is the whole appeal. This guide covers racing it, and training on the Riviera that makes it possible.
The Course
The Swim: 3.8km in the Baie des Anges The race starts in the Mediterranean off the Promenade des Anglais. The Baie des Anges is a wide, gentle bay; the water is clear and typically warm, with conditions that range from glassy to moderate chop depending on the morning. The swim is a loop (or double loop) marked off the seafront, finishing back at the Promenade for the run into T1. Sighting is straightforward against the backdrop of the city and the hills. For most athletes this is among the more pleasant IRONMAN swims on the calendar.
The Bike: 180km into the Alpes-Maritimes This is the course's defining leg and the reason Nice is a championship venue. The route leaves the coast within the first few kilometres and climbs into the backcountry behind Nice — the **arrière-pays** of the Alpes-Maritimes.
The signature climb is the Col de Vence, a long, exposed ascent out of Vence into the high limestone plateau country around Coursegoules. The route works through the Gorges du Loup region — a landscape of deep gorges, perched medieval villages, and the kind of quiet backcountry roads that make this corner of France a road cyclist's destination in its own right. There is sustained climbing here: long ascents that reward riders who can hold power for 30–40 minutes at a time, followed by technical descents back toward the coast.
The bike leg is not a course for raw flat-road power. It rewards climbing, pacing discipline, and the bike-handling to descend the Alpes-Maritimes roads at speed. Athletes who overcook the early climbs pay for it on the run.
The Run: Four Laps of the Promenade After the mountains, the marathon is flat — four laps of the Promenade des Anglais along the seafront. Flat does not mean easy: the laps are run in the heat of a Riviera afternoon, fully exposed, with the accumulated fatigue of the swim and a mountainous bike leg. The crowd support is constant — the Promenade is lined for the full marathon — and the four-lap format means you pass the finish chute repeatedly before you are allowed to take it. The finish is on the Promenade des Anglais, in the Mediterranean evening.
Training on the Riviera
Nice is one of the best endurance training bases in Europe, which is why pro triathletes and cyclists winter here.
Cycling: The Col de Vence is the benchmark local climb and part of the race route — ride it. Beyond it, the Alpes-Maritimes offer endless backcountry: the Gorges du Loup, the climbs around Coursegoules and Gourdon, and the higher cols deeper into the range. The coast road gives flat tempo riding; the hills behind give everything else.
Swimming: The Baie des Anges is open-water-swimmable for much of the year. Many athletes do their open-water work directly off the Promenade.
Running: The Promenade des Anglais itself is the run course — flat, measured, and ideal for race-pace work. For trails, the hills behind the city climb quickly.

By air: Nice Côte d'Azur Airport (NCE) is 7 kilometres from the race start — one of the most convenient airport-to-venue setups in the IRONMAN calendar. It is a major international hub with connections across Europe and beyond.
By train: Nice-Ville station is on the French high-speed network, with direct TGV connections to Paris (around 6 hours) and regional services along the coast to Monaco, Cannes, and the Italian border.
Getting around: Central Nice is walkable, and the tram network connects the station, the old town, and the seafront. A bike is the ideal way to reach the training roads behind the city.
Where to Stay
Central Nice / Promenade des Anglais: The obvious race base — walk to the swim start, the run course, and the expo. Range from seafront luxury (the Negresco and its neighbours) to mid-range hotels a few streets back (€100–200) and apartment rentals in the old town (Vieux Nice).
Vieux Nice (old town): Atmospheric, central, and walkable to everything — book early for race weekend.
Up the coast (Villefranche, Beaulieu) or back from the front: Quieter and sometimes cheaper, with easy tram or train access to the start.
Book well ahead for race week — Nice in late June is peak Riviera season independent of the race.
Local Tips
Eat: Niçoise cuisine is built for athletes — socca (chickpea pancake), pan-bagnat, ratatouille, and the salade niçoise done properly. The Cours Saleya market in Vieux Nice is the place to graze. Post-race, the old town's restaurants and the seafront brasseries handle the celebration.
The rest day: The coast rewards exploring — Villefranche-sur-Mer, Èze perched above the sea, Monaco fifteen minutes east by train. Or simply the beach: after an IRONMAN, the Baie des Anges is exactly where you want to be.
Recovery: The Mediterranean itself is the recovery tool — a cold-ish sea swim the day after does more than any device.
