Trail des 2 Baies, or Trail D2B, is a coastal trail race on the Côte d’Opale in northern France. It begins early in the morning from Le Touquet-Paris-Plage and is a 100% nature event, with runners and walkers participating in the colder part of the year.
The race focuses on beach and dune running: soft, shifting sand in the dunes, firmer sand on the beach, and rough weather that can make the coast feel exposed. It is intended for those seeking a challenging outdoor run over a polished road race, and the event is approaching its twentieth edition.
