Source and method

Course: Mid South 2026 50 Mile, published by The Mid South. Retrieved 2026-10-12. 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.
