White shirts and red scarves define the Foulées du Festayre's appearance before participants depart. This race series takes place in early July in Bayonne, Pyrénées-Atlantiques, France, featuring a 13.9 km trail run and an 11 km walk. The event connects with the Southwest festival atmosphere, and locals consider it practical preparation for the férias. Over 4,000 people participated in the last edition, indicating a large public gathering rather than a small club event.
The trail begins on Boulevard du Prince de Galles, passing through Biarritz, Anglet, and Bayonne before concluding at Quai de Lesseps. The course navigates the old port of Biarritz, enters the Chiberta forest in Anglet, and combines coastal, urban, and natural landscapes within a single loop. The 13.9 km run involves 88 m of elevation gain and 88 m of descent, presenting moderate hills. The 11 km walk has distinct start and finish locations, and July weather near Biarritz can bring unexpected rain.
