02·Course by Section
A two-loop saltwater swim in the clear Mediterranean Sea featuring an Australian exit across a painful pebble beach. High salinity makes you buoyant but demands early hydration management.
A highly demanding mountainous course featuring the Col de Vence and the Col de l'Ecre climbs in the inland hinterlands. The final section requires negotiating technical high-speed switchback descents on narrow roads.
A flat, four-loop marathon along the coastal road between the transition and the Nice airport. With zero shade, the heat off the asphalt and the blistering sun turn this flat profile into a severe challenge.

With afternoon temperatures exceeding 30°C and zero shade on the run, cooling is paramount. Grab ice and wet sponges at every 1.7 km aid station, and use high-SPF sunscreen to combat the intense Mediterranean sun.
Consume the majority of your targeted carbs and fluids during the long uphill climbs on the bike, as the fast, technical descents make eating difficult. Rinse your mouth with fresh water immediately after the high-salinity swim.
Protect your legs during the front-loaded bike climbs like Col de l'Ecre, aiming for a steady effort. Do not over-pace the technical descents, and prepare for a patient, metered effort on the flat, blistering hot marathon.
Consider a road bike with clip-on bars for optimal climbing and technical descending control. Bring old socks or flip-flops to wear on the painful beach pebbles at the swim start, which you can discard before entering.
The bike course is extremely difficult, featuring a single 180 km loop with a massive 2,200m to 2,400m of elevation gain through the Alpes-Maritimes hinterland. The climbing is heavily front-loaded, highlighted by the Col de l'Ecre, a challenging 13 km climb averaging 4.9% grade to the course's highest point. The final 50+ km are highly technical, containing high-speed descents with narrow roads and switchbacks that require excellent bike-handling skills.
The water temperature in the Mediterranean's Baie des Anges typically ranges between 20°C and 22°C (68°F to 72°F). While this range is usually wetsuit-legal for age group athletes, it can occasionally flirt with the 24.5°C non-wetsuit cutoff in warmer years. Be prepared for a saltwater, two-loop swim with a rolling beach start on the painful pebble shore of Plage du Centenaire.
You should front-load your heavy caloric intake and hydration on the long uphill climbs of the bike course's first 90 to 112 km, as the subsequent technical descents are too fast and twisty to safely eat or drink. On the run, you must focus on taking in sodium, electrolytes, and water at every aid station spaced 1.7 km apart to combat the intense Mediterranean heat. Additionally, drink fresh water pre-swim to wash out the high-salinity seawater.
The run is a completely flat, 42.2 km marathon consisting of four identical out-and-back loops along the paved Promenade des Anglais. While the flat asphalt offers a fast profile with under 30 meters of total elevation gain, there is absolutely zero shade. Because peak afternoon temperatures can easily exceed 30°C (86°F), it becomes a physical war of attrition where you must use ice and wet sponges to manage your core temperature.
You should fly into Nice Côte d'Azur Airport (NCE), which is highly convenient as it sits only 7 km from the transition area. We highly recommend booking a hotel within walking distance of the Promenade des Anglais because major race-day road closures make driving and parking extremely difficult. Additionally, pack an old pair of socks or flip-flops to wear on the painful beach pebbles at the swim start, which you can discard right before entering the water.
