Saint-Nazaire

Saint-Nazaire sits on the Loire estuary in Brittany, where flat coastal terrain meets the Atlantic wind. Cyclists dominate here—the Gravel de Retz from nearby Saint-Brevin-les-Pins (80km) showcases the region's gravel backroads and salt marshes, while longer events like the Rallye Cyclotourisme (98km) roll through the bocage inland. Runners find the coast mostly pancake-flat with tidal exposure; local options center on seafront loops rather than established marathon courses.
