According to the International Association of Ultrarunners and Ultrarunning Magazine, with preliminary results for the IAU 24 Hour World Championship in 2019, she holds the World Best performances at the following distances:

As of October 2019, she has set nine Open American Records (50 Mi Road Best, 50 Mi Track, 100K Track, 12Hr Track, 100 Mi Road, 100 Mi Track, 200K Track, 24Hr Track and Road) and three IAU-recognized Open World Bests (100 Mi, 12Hr, 24Hr). In October 2015, she set an unofficial 50 mile world best of 5:38:41 at the Fall 50, surpassing Ann Trason's 5:40:18 performance from 1991. Her 100 Mile Women’s World Best of 12:42:40 at the 2017 Tunnel Hill 100 is also the fastest women's time on trail, averaging 7:37 per mile. For her 100 Mile and 24Hr World Bests, she won the races outright beating all of the men. She was the top ranked American 24Hr runner, including both men and women, going into the 2019 IAU 24 Hour World Championship, where she won her third World title and bettered her 24-hour World Best by running 270.116 kilometres (167.842 mi).

As an ultrarunner, she's won four USATF titles (50K Road, 50 Mi Road, 100K Road, 100K Trail). In 2015, she became the first ultrarunner to win two World titles in the same year, winning the IAU 100 km World Championships and the IAU 50 km World Championships. In June 2017, she became only the 3rd American to win the Comrades Marathon, leading from start-to-finish. In a memorable finish, she accidentally stopped at the wrong timing mat after receiving the penultimate baton and rose. A male runner came from behind, tapped her on the shoulder, and pointed that she wasn't done yet. She went into a sprint the final 200m to win.

She was voted the 2015, 2018, and 2019 IAU International Athlete of the Year. She is also a five-time honoree of the USATF Ruth Anderson Ultrarunner of the Year award, six-time USATF Athlete of the Week honoree, the 2017 Ultrarunning Magazine Female Ultrarunner of the Year, and four-time Ultra Performance of the Year.
