At the 100-mile marker, Courtney Dauwaulter would typically be celebrating her race victory, but this time, she's got another 156 miles to go on the Cocodona 250 course.
Back in January, the reigning queen of ultra running announced she was leaving the 100-mile distance behind for a few months to try her hand at the 250-mile distance. On Monday morning at 5am, she took off along with 308 other runners in a race from Black Canyon City north of Phoenix to Flagstaff, Arizona.
