Course Nature de la Grapille

Course Nature de la Grapille sends runners up the heights above Torpes, a small commune in the Doubs department of Bourgogne-Franche-Comté in eastern France. Held in early November, it is a nature race with trail runs of 7 km, 13 km, and 20 km, plus a 5 km walk and separate courses for children and juniors. The longest route is a single 20 km loop with about 440 to 450 metres of climbing, while the 13 km course has 300 metres of gain and draws the biggest field, with more than 200 runners in the previous edition. The 7 km option climbs 110 metres and had more than 100 participants last time, so the event works for local trail runners, walkers, younger athletes, and people who want a shorter race on the same November race day.
