The Valais is renowned far and wide for its mountains. However, for this marathon we're offering you the chance to contemplate them from the plains, by proposing fast races with little difference in altitude. On the mythical Marathon distance, link the magnificent old town of Sion to the Roman city of Martigny, immersed in Valais nature and surrounded by more than 10,000 hectares of orchards and vineyards along the banks of the Rhône. You can also experience the 21km, 10km, 4km, 2.5km or 1.5km loop from the CERM in Martigny.
