Event Overview
On Tuesday, May 5, a female runner in her 40s collapsed at the Groom Creek trailhead south of Prescott, Arizona, during the 2026 Cocodona 250 ultramarathon. Yavapai County Sheriff’s Office spokesperson Paul Wick said first responders attended the scene and that the death was non-suspicious; no foul play was identified. The runner’s name and medical condition were withheld at the family’s request.
Course Profile
The Cocodona 250, organized by Aravaipa Running, begins in Black Canyon City (?20 mi north of Phoenix) and ends in downtown Flagstaff. The route covers roughly 250–253 miles, climbs more than 38,000 feet (officially 38,791 feet) of elevation, and reaches a high point of 9,241 feet on Mount Elden. Aid stations and medical teams are positioned along the trail; participants have 125 hours to finish. Approximately 395–400 runners entered the 250-mile division in 2026.
Key Participants and Responses
Cocodona 250 codirector Erika Snyder confirmed the death and declined further comment. American ultrarunner Rachel Entrekin won overall with a time of 56 hours 9 minutes 48 seconds, becoming the first woman to claim the overall title. The race continued after the incident, with organizers urging participants to honor the fallen runner.
Official Statements
Organizers posted a statement expressing sorrow, confirming that the runner’s family and crew had been notified, and stating that the race would proceed in her honor. The sheriff’s office emphasized that the incident involved no criminal activity.
Safety Concerns
The death has renewed debate over ultramarathon safety. Prior incidents include a 2025 Michigan runner’s death during a 102-mile Colorado race and the 2021 loss of 21 competitors in a Chinese ultramarathon amid extreme weather. Experts note that despite on-course medical support, prolonged exposure and extreme elevation changes pose inherent risks.
Conflicting Reports
Sources list the distance as 250, 253, or 253.3 miles; participant numbers vary between “nearly 400,” 395, and 400; and the collapse is dated Tuesday May 5, while the public announcement appeared on Wednesday May 6. No cause of death or identity has been released.
