Lore & Trivia
Cocodona 250 traverses Arizona from Black Canyon City to Flagstaff — 400km through the full elevation profile of the American Southwest, from Sonoran Desert (600m) through chaparral, pine forest, and up to the San Francisco Peaks (2,700m). Created in 2021, it's one of the youngest 200-milers but already considered one of the toughest, combining desert heat, mountain cold, significant altitude gain, and the sheer volume of 250 miles. The name comes from combining "Coconino" and "Sedona" — two of Arizona's most dramatic landscapes that the route traverses.

Notable Editions
The First Cocodona
The inaugural Cocodona 250 in 2021 immediately established itself as one of America's toughest 200-milers. The combination of desert heat, high-altitude cold, and 250 miles broke even experienced multi-day runners. The dropout rate was severe, but the course's beauty — Red Rock, Sedona, and the Coconino Plateau — made the suffering worthwhile.
