Ashley Paulson Smashes 100-Mile World Record
Ashley Paulson of the United States set a new women's 100-mile world record, clocking 12:19:34 at the 2026 Jackpot 100 Mile race. The performance shattered the previous record and raises the bar for ultrarunning worldwide.
- The previous women's 100-mile world record was 12:37:04, set by Caitriona Jennings of Ireland at the 2025 Tunnel Hill 100 Miler. Paulson's time of 12:19:34 was more than 17 minutes faster. - The Jackpot 100 Mile race, held in Henderson, Nevada, also served as the USATF 100 Mile National Championships. - Paulson maintained an average pace of 7:21 per mile over the 100-mile distance. She started aggressively, with splits around 7 minutes per mile for the first 20 miles. - The course at Cornerstone Park is known for being fast, run on a 1.19-mile loop that is mostly asphalt and crushed gravel paths with minimal elevation change. - This is Paulson's first world record. She is also a two-time champion of the grueling Badwater 135, widely considered one of the world's toughest foot races, and holds the women's course record for that event. - Paulson, a 44-year-old mother, has an extensive endurance sports background, having competed as a professional triathlete and run over 130 marathons. In 2020, she placed 44th in the U.S. Olympic Marathon Trials. - This was not Paulson's first time at the Jackpot 100 Mile; she won the event in 2024 but did not finish in 2025. - In 2015, Paulson received a six-month doping sanction during her triathlon career for a positive test for ostarine, which she attributed to a contaminated supplement.
