Course & terrain
The Marathon de Nantes is a very flat loop starting and finishing on the Île de Nantes, passing the Château des Ducs de Bretagne, the Erdre and Loire rivers, and views toward Trentemoult. The riverside and island stretches are easiest to run smoothly, while the exposed bridge crossings and long urban straights are tougher late on; support is strongest on the Île de Nantes, around the château, and along the Loire embankment.
The Marathon de Nantes course is flat over 42.195 km (26.2 miles). Runners cover 50 metres of climbing and 50 metres of descent, with minimal net elevation change from start to finish.
Registration
The Marathon de Nantes uses open registration at marathon-nantes.fr with no ballot or qualifying standard. Sign-up for the April race typically opens the previous autumn. The Loire river course draws strong western French participation and early registration secures lower tier pricing.
