Fyne Terra Semi-Marathon

The Fyne Terra Semi-Marathon is an annual half marathon (21.1 km) in Yverdon-les-Bains, canton of Vaud, Switzerland, on the shore of Lake Neuchâtel. First held in 2012 (building on the Fyne Nature Marathon that began in 2008), the race reaches its 14th edition in 2027. The Swiss Athletics-certified, officially measured course mixes road and path, crossing wooden footbridges along the lakeshore and the surrounding Jura-Nord Vaudois countryside. Alongside the half marathon and its two-person relay (2 x 10.55 km), race day includes an 8.5 km running and Nordic walking course plus two children's races (2.3 km and 1.15 km). The 2026 edition drew more than 300 runners on May 30; the next edition is provisionally set for Saturday, May 29, 2027.
