Rachel Entrekin has set a record in the Cocodona 250 ultramarathon, reportedly fueled by mashed potato and minimal sleep. She is also the first woman to win the event, outrunning the entire men's field in the process. The exact details of her achievement vary, but it is clear that Entrekin's performance was a historic one, with some reports indicating she completed the 250-mile race in 56 hours on very little sleep.
