The Hungry Bear 100 is 100 miles of gravel roads through northern Wisconsin’s Chequamegon, rolling to hilly with roughly 5,000 feet of climbing. It runs in early May, when the day can start with a cold, raw rollout and warm through the afternoon, with rain in play.

This is a twelve-week plan for riders chasing a result, built around the higher weekly hours that racing a hundred miles takes, not just finishing it. The volume is higher and the hard days more specific, because a result over rolling gravel comes from holding pace through the repeated climbing, not just covering the distance.
