JuraSwimRun - 15 km 2026

JuraSwimRun is a swimrun event in France's Jura region. The 15 km race is called Défi Terre d'Emeraude and takes place in September. It combines running with open-water swimming, requiring participants to transition between land and water multiple times rather than completing a single continuous discipline. The event also features a 35 km race, Défi du Hérisson, establishing a short-course and long-course format. The organizer offers a teammate-finding link for individuals seeking a partner, a practical feature aligned with swimrun culture where many races are contested in pairs and teamwork is as crucial as speed.
