This is the race you need if you want to discover the Trail de l'Etendard while staying in Bourg d'Oisans. You will start with a 3 km loop crossing the plain of Bourg d'Oisans, thus offering a breathtaking view of the Grandes-Rousses massif and allowing you to warm up gently before facing a first ascent to the Puy supply station. . Almost all the elevation is done on this coast, with 350 meters of elevation gain over 1 km, but you will be rewarded with breathtaking views of the plain below. Once you have arrived at the Le Puy supply station, you will begin a 14 km route with two additional climbs which will give you access to the loop of the Lac de Buclet, located at the gates of the mythical Vénéon valley, for even more landscapes.
