Hannah Otto is one of the leading lights in US ultra-endurance and marathon MTB racing — multi-time national marathon MTB champion and holder of the Kokopelli Trail FKT she set in 2024 (130 miles in 13 hours, 49 minutes). She races a mixed calendar of marathon MTB, ultra-distance gravel including Unbound 200, and select FKT projects. For Roadman listeners, her perspective on training for events that mix steep, technical terrain with 8+ hours of pacing is one of the cleanest in the sport.
