The trail starts gently along the Isère riverside to Guy Pape Park before climbing to La Bastille on a shaded path.
After a few flights of steps that remind you these are fortifications, you'll reach the outer rampart wall. Before returning to the riverside via Guy Pape Park, you'll be rewarded for your efforts with a panoramic view over the city and the surrounding mountains as you pass below the "Bubbles" of Grenoble's cable car.
You'll find water at Porte Saint-Laurent, La Rochette and Quai Saint Laurent.
The calculation of the difﬁculty of each course takes into account the length, the positive vertical drop, the greatest continuous positive or negative vertical drop as well as the technicality of the terrain.
All year round.
