The Munster Trail is an October trail-running series held in the Fecht Valley, located in the High Vosges of eastern France. The races take place within the Ballons des Vosges Regional Natural Park in Haut-Rhin, offering four primary distances: 10 km, 20 km, 40 km, and 100 km. The shortest distance involves a 500-metre climb, and the 100 km route features 5,200 metres of elevation gain.
The courses traverse mountain terrain surrounding high-altitude lakes, incorporating technical sections that demand more than basic road-running ability. The 20 km route ascends 900 metres, and the 40 km route gains 1,800 metres, indicating that the intermediate distances are also substantial mountain challenges. The race's unique terminology reflects a spirit of resilience and grit, encouraging participants to demonstrate strong character and persevere through potential October rain to achieve a rewarding run.
