Jackpot Ultrarunning Festival – Henderson, Nevada

The 100-mile race on Friday, February 20, was contested on a 1.19-mile loop and was the USATF 100-Mile Road National Championships. There was a $4,000 prize purse.

It was a three-peat for Rajpaul Pannu in the men’s race.

In the men’s race, Rajpaul Pannu came back from a disqualification in 2025 to win in 11:38. In 2024, Pannu also won in 11:58, but in 2025, he finished first in 11:52 but was disqualified from the championships when his shoes didn’t meet USATF standards. This year, Pannu came through halfway in 5:37 and averaged just under seven minutes per mile for the full 100 miles.

The next three men all went sub-14 hours, too. Scott MunsonEdher Ramirez, and Pete Kostelnick ran 13:37, 13:44, and 13:57, respectively.

The day really belonged to women’s winner Ashley Paulson, though. The 44-year-old from Utah scored a new women’s 100-mile world record. Paulson ran 12:19 to take 17 minutes off Caitriona Jenning’s (Ireland) old record from November 2025. Paulson ran the first half in 5:56.

Paulson first burst into ultrarunning with a win at the 2022 Badwater 135 Mile and earlier won the 2024 Jackpot Ultras 100 Mile in 14:04. A prolific runner, Paulson is next signed up for the Arizona Monster 300 Mile in late March, and then the 200-Miler Triple Crown: the Tahoe 200 Mile, Bigfoot 200 Mile, and Moab 240 Mile across this summer and fall.

Second- and third-place Kaylee Frederick and Jenny Arnzen ran 14:49 and 15:01 to get on the podium.

[Ashley Paulson served a six-month doping sanction in 2015 and 2016 due to a doping violation in triathlon for a positive test for ostarine, a selective androgen receptor modulator (SARM) from a contaminated supplement.]

Call for Comments

  • I love this story. Little-known American Ethan Shuley ran 2:07:14 at Japan’s Osaka Marathon on February 22. That made him the seventh-fastest American ever at the distance. The article included a trail tie in. “When he got to Japan, he was not chasing 2:07. He wanted to run a trail ultramarathon, thinking that slower, longer running might keep him healthy. He attempted a 100-mile trail race with roughly 20,000 feet of climbing but dropped out at mile 60.” That trail race appears to be the 2023 Lake Biwa 100.
