Bike and Run de l'Ile Madame is a mid-March sea-side Bike and Run in Port-des-Barques, Charente-Maritime, on France's Atlantic coast. Teams race as duos: one person runs while the other rides, and they can swap the bike whenever they want. The main distances listed are 8 km and 15 km, with separate routes for children and juniors.
The route is mostly on nature trails and makes a tour of Ile Madame, a small island setting that gives the event its unusual feel. Parts of the course pass by the sea and through a public park, and organizers warn that one section may be a little wet. OCEAN TRIATHLON runs the event, registration is online only, and there are no sign-ups at the venue.
