Course des 100 Marches 2026

The 100 Marches Race is a concentrated version of Biarritz, an out-and-back course between the ocean, the city, and nature, with one obsession: climbing the famous steps of the Côte des Basques and descending them repeatedly. The concept is simple and addictive: participants start together on a 1.1 km loop, climbing the steps and descending via switchbacks. With each lap, the pace intensifies. The challenge is to stay calm as your legs burn and the salty air hits your face. Biarritz reminds you that the Côte des Basques can be tough but classy. The course requires strategic pacing, starting with familiarizing yourself with the switchbacks and saving energy for when the pace quickens. It's a race of levels, fitting for a course with many steps. After the race, enjoy nearby attractions such as the Rocher de la Vierge, the Biarritz Lighthouse, the Port des Pêcheurs for its atmosphere, and the Casino Barrière and the seafront. For couples or families, a sunset on the Côte des Basques or a walk towards Bidart offers a postcard-perfect experience.
