At the inaugural Mammoth 200-miler in Mammoth Lakes, Calif., Rachel Entrekin of Madison, Ala., delivered a performance for the race’s history books. The 33-year-old covered the gruelling 214-mile (344 km) course in 46 hours, 50 minutes and 55 seconds to win her 18th consecutive ultra, set the women’s record and finished second overall.

The only runner to finish ahead of her was California’s Jimmy Elam, who took the win on his home course in 45:16. With the win, Entrekin pocketed US$5,000 prize for being the first woman across the line, completing the mountainous loop that featured nearly 9,500 metres of climbing.
To put her effort into perspective: Entrekin averaged 8:10 per kilometre for almost 47 hours straight. She crossed the line looking unfazed, even joking with the crowd: “That was fun…who’s in for one more loop?”
This marks the second time this year Entrekin has put her name in the record books at a 200-miler. In May, she won the Cocodona 250, shattering the women’s course record by more than seven hours.
At Mammoth, she went stride for stride with Appalachian Trail FKT-holder Tara Dower for 80 miles before Dower dropped out. From there, Entrekin built a commanding lead over the women’s field, ultimately winning by nearly nine hours. Fellow American ultrarunner Amber Weibel finished runner-up in 55:40, while Kallie Smith rounded out the podium in 63 hours.
The field also featured Canadian ultrarunning YouTuber Jeff Pelletier, who placed eighth overall in 57 hours and 55 minutes.
