Organizers of the 2026 Cocodona 250 said late Tuesday night that a participant experienced a medical emergency and died during the race, turning one of the sport’s most grueling events into a night of shock and grief in Arizona.
Race founder Jamil Coury said the team was not releasing additional personal details at that time and was supporting those directly involved. He said the race would continue in the runner’s honor, asking participants and crew to carry the memory of the runner with them on the trails through the rest of the week and beyond.
The death came during the sixth edition of the 253-mile race to Flagstaff, a mountain-tested event that has risen quickly in ultrarunning over only six years. This year’s field included four past champions, among them Rachel Entrekin, the two-time winner and defending champion, Michael Versteeg, who won in 2021, Joe McCounaghy, who won in 2022, and Michael McKnight, who won in 2023.
By night two, Entrekin was still setting the pace. She came into Munds Park, at mile 190.6, in the overall lead and on pace for the course record she already owns at 63:50:55. Elsewhere on the course, Kilian Korth hobbled into Munds Park with a glute that “isn’t working,” while Cody Poskin carried a healthy gap over Heather Jackson, who was making her debut over 200+ miles. The race was unfolding in rain and cold.
The front of the field also tightened at Schnebly Hill aid station, where four runners were in the area at once fighting for fifth place: Courtney Dauwalter, Zach Hauer, DJ Fox and Joe McConaughy. Dauwalter had DNFed at mile 108 last year, a reminder of how unforgiving the Cocodona 250 can be even for the sport’s biggest names.
Coury’s decision to keep personal details private left the race suspended between competition and mourning, with the course still moving but the mood changed in an instant. For a race that has built its identity on endurance, the next miles now carry a different meaning for everyone still out there.
