“Why not you?” — That’s the mantra Rachel Entrekin repeated in her head as she made ultramarathon history.

Entrekin, 34, beat every man and woman in the Cocodona 250 Mile on Wednesday in Flagstaff, Arizona.

As she set a course record of 56 hours, 9 minutes, and 48 seconds, she also ran faster than Kilian Korth, who set a men’s course record of 57:28:36.

Before Entrekin, no woman had ever won the event overall in the race’s history.

It was Entrekin’s third straight year winning the award, but she ran more than seven hours faster this time around.
