Grinduro France is 62 miles with about 6,500 feet of climbing in the Vosges mountains, run in an enduro format where the climbs are untimed and four descents are timed on steep, technical, forested terrain — half gravel, roughly a third singletrack. The weather is generally warm, but mountain conditions can change.

This is a twelve-week plan for riders fitting training into seven to eleven hours a week. Most of the work builds endurance for repeated climbing over sixty-plus miles and the bike handling that timed technical descents ask of you.
