Marathon relais 2026

The Marathon Relais divides a full marathon into three legs for a team of three runners, beginning at Parc des Sports d’Aguiléra in Biarritz at 7:00 AM. Each teammate runs a distinct section, creating a shared point-to-point journey: one runner starts from Biarritz/Aguiléra to Bassussarry for 14 km, the second covers 16 km to Bidart’s Erretegia area, and the third runs 12 km back to Biarritz. The course crosses Biarritz, Arcangues, Bassussarry, Arbonne, and Bidart before returning along the ocean front. With 480 m of total elevation gain, the route is not flat. Eight aid stations are available on a course that combines town streets, Basque countryside, village sections, and coastal paths. Teams must also monitor time cutoffs; the course closes at Ilbarritz around km 32, with the finish closing later in the afternoon.
