Do you want to stop swimming to devote more time to running? Another athlete who doesn't know about SwimRun! 🤓 Whether solo or in pairs (as per the tradition of SwimRun), you will tackle a challenging course that alternates running and swimming sections without transitions. No time to change: you'll run in your wetsuit and swim in your shoes! 👟 For that, head to the Gorges de Loire in Saint-Victor-sur-Loire, between Lyon, Saint-Étienne and Grenoble, at the crossroads of the Loire and Haute-Loire in Auvergne-Rhône-Alpes. Waterfalls, rivers, lush nature 🍃, what better playground to test this new race format? 😎
