One of IRONMAN's most scenic courses is also one of its hardest with over 2400 meters of total elevation gain.  The bike course has two major climbs, the Col de l'Ecre (km 40) and the Côte de Coursegoules (km 112) as you ride up into the southern Alps before looping back around to the beach.  IM Nice has the steepest .5km, 1km, 5km, and 10km segments of any 140.6 on earth.

However, the good news is that once you complete the climb to Coursegoules, there are less than 100 meters of climbing for the remainder of the bike - a fast 50 kilometers! The run course is the flattest Ironman run on earth, having only 29 meters of elevation gain over the entire marathon.

This race takes place simultaneously with 70.3 Nice, with the Half Ironman swim starting a couple hours after the full. The two transitions are next to each other.

We really recommend staying at a hotel within walking distance to Transition for this one. Parking is a nightmare, since in addition to the closed roads and thousands of others trying to find parking, it's also downtown Nice.  Here are a few close parking lots to look for if you get lucky:
