The Int. Martinslauf is an annual community road race in Losheim am See, with the village center and the Losheim reservoir serving as the event setting. It features 2 km, 5 km, and 10 km races, suitable for children, newer runners, and those seeking a standard 10K effort.
The routes encircle the reservoir, closely connecting the course to one of the town’s primary outdoor locations. Up to 1,500 runners participate, with registration open until shortly before the start. TV 1929 Losheim e.V. organizes the race as a regular fixture in Saarland running.
