From the Mediterranean to the Atlantic , this cycling crossing of the Pyrenees is a unique adventure for cycling enthusiasts and lovers of wide-open spaces. In 8 stages , you'll traverse the Pyrenees mountain range through 5 departments , tackling legendary Tour de France climbs: Portet d'Aspet, Peyresourde, Tourmalet, Aubisque, and Marie-Blanque . From the very first pedal strokes in Collioure , the Mediterranean landscapes give way to the wild valleys of the Ariège , before reaching the high peaks of the Hautes-Pyrénées . Every climb is a challenge, every descent a reward, every turn a new perspective on this unspoiled nature. Then, the terrain softens as you enter the Basque Country , where the sea air becomes more prominent as you approach Saint-Jean-de-Luz . This journey is much more than a simple sporting challenge: it's an immersive experience where the beauty of the landscapes blends with the satisfaction of pushing your limits. By linking the sea to the ocean using only the strength of your legs, you will experience the very essence of adventure cycling , a blend of effort, emotion, and wonder .
