C. Prudhomme's comment
The start of the 105th edition will be given at Noirmoutier-en-l’île. On the sea shores of Vendée, riders will need to be extra careful if the wind is blowing as they go through Saint-Gilles-Croix-de-Vie or les Sables-d’Olonne. It’ll also be the case when the peloton enters the Poitevin marshlands. A total of around 110 kilometres will be covered by the sea.
