This course is compact and steep, offering a challenging run rather than a simple woodland jog. The 13 km race is one of several distances in the Trail de la Vallée des Lacs series, which also features 24 km, 43 km, and 82 km events. This shorter option is also known as La Natur'Elle de Marie. It is included within the same trail-running program as the longer mountain races, providing a demanding introduction to the event for those not wishing to commit to an ultra-distance.
