The Filthy 50 is 50 miles with about 2,000 feet of climbing on rolling roads that are mostly gravel with some dirt, through northern Minnesota’s lakes country in early October. Expect fall conditions in the 40s to 60s with a chance of rain.
This is a six-week plan for riders whose entry is paid and whose weeks are short. Six weeks can’t build the distance from scratch, but it can prioritize the limited hours toward steady riding on rolling gravel and getting used to time in the saddle, so the plan gets you to the start with a clear structure for the fifty miles.
