Dizzy Fifties
Huntsville, United States • 15 Nov 2025
Dizzy Fifties, in its 22nd year, is a grassroots trail race at Monte Sano State Park in Huntsville, Alabama. It offers three distances: a 50K (three ~10-mile loops with ~1,000 ft of climbing per loop and ~3,000 ft total gain), a 20-mile, and a 10-mile option. All distances follow the same figure-eight loop starting and finishing at the John Scoble Memorial Pavilion.
The course includes the South Plateau, Firetower, Logan-Keith, and the Sinks climb, with a cupless format and a single fully stocked aid station. Medical support is on-site, parking is limited, and the event maintains a welcoming, community-first vibe. The 50K counts toward the Huntsville Slam Series.
