Course: 2027 75mi Old Man Winter RIDE, published by Old Man Winter Rally. Retrieved 2026-10-27. RideMorrow is not affiliated with the event. Organizers change courses, so check the official site before the event.
Elevation comes from the route file, resampled every 10 m and smoothed. Climbs and descents need at least 300 m of length, 20 m of elevation change and a 2% average grade. Grades are measured over 100 m. Climbs are ranked by FIETS score: height² ÷ (length × 10), both in metres, without the index's high-altitude bonus. A score of 1 is a solid climb; 5 and above is a mountain pass. Weather, surface conditions, traffic and closures are not included.
