Starting from the village of Saint-Cergue, famous regional ski and hiking resort, the “medium” LG Trail offers a more accessible route than the full track and will take you directly to the crests of the Jura mountains.

The course is divided into 2 different sections :

The crests : This is a true wall directly into the ski slope that you have to climb as a warm-up. A lot of local people will encourage you to help you making it. Your objectives are a bit higher in altitude : la Barillette and la Dôle, 2 famous regional tops. Uphill, on one side, you can see forests beyond the horizon that will let you imagine how wide is the Jura. On the other side, probably the most outstanding mountain view in Europe with a 180° vision on the Alps chain from Grenoble to Bern and further. In the middle, the Mont-Blanc stands like the boss and looks at you. This is the highest point of the race. What’s next is a steep long downhill where the descent experts will have extreme good fun. You have to go uphill again and cross the french boarder at the top of Divonne-les-Bains before climbing the cute Mont Mussy. You enter again in Switzerland when crossing the bridge of the Versoix river and reach the full of support Chavannes-des-Bois village before entering the final part. The hardest is behind you.

The plain : You enter a flatter final part with the discovery of a true natural jewel of the Geneva’s countryside : the Versoix river. This is true fun that you are being offered despite the fatigue in a dynamic single path with little bumps. You will even see secret beaches into the forest. After reaching green fields hosting horses, buffalos and deers, you cross the motorway and enter slowly the city of Geneva by the parks of Château de Penthes and Jardin Botanique. You finally cross the finish line in front of the legendary water jet where you will be waited by a high number of people standing here to encourage the last efforts of a great adventure. Celebrate with your friends, your family and our volunteers. Have a cold beer, a plate of raclette cheese and help yourself jumping in the lake for a well deserved bath at the Bains des Pâquis.
