Both Course Records Fall at Rain-Soaked Run Rabbit Run 100

Ryan Sullivan and Hannah Allgood shattered the Run Rabbit Run 100 course records through a night of hard rain, each winning $20,000 in Steamboat Springs.

The 14th edition of the Run Rabbit Run 100 Mile above Steamboat Springs, Colorado, ended with both course records broken on Saturday, September 19, 2026. Ryan Sullivan won the men's Hare division in 17:03:38, and Hannah Allgood took the women's race in 19:01:59, each earning $20,000 from the race's $100,000 purse. Race director Fred Abramowitz told the Steamboat Pilot & Today, "They both shattered course records and won by over an hour each. It's incredible." Sullivan's time took nearly 19 minutes off Dave Stevens' 2023 record of 17:22:34, while Allgood ran 46:06 inside Emilie Mann's 19:48:05 from 2024. Over 800 runners took to the Yampa Valley trails for the event.

The conditions made the records remarkable: the Hare field went off at 1 p.m. on Friday, the weather broke within hours, and most of the following 12 hours of darkness were wet, wet enough that Marathon Handbook reports several leading women took extra time at aid stations to get warm before going back out. The course climbs 20,391 feet over 101.5 miles and tops out above 10,500 feet, so both winners ran the bulk of their race by headlamp. Sullivan's improvement is arguably the more dramatic: a year earlier he finished fourth on the same course in similar weather in 19:29:32, so he took 2:25:54 off his own time. Sullivan told iRunFar, per Marathon Handbook, "I was just very, very ready for it this year," and said he carried record splits for his crew rather than keeping them in mind while running.

Sullivan first took the lead from Jeff Mogavero climbing away from Fish Creek Falls at mile 17.6, and the gap grew in degrees: three minutes by Long Lake at mile 24 and nine by Summit Lake at mile 30, according to Marathon Handbook. He finished 55:36 ahead of Mogavero (17:59:14), with 2025 winner Jesse Rich third in 18:18:47 after running part of the night with a failed headlamp. Allgood shared the lead with Isabella Poulos over the opening climb, went clear on the long descent to Fish Creek, and won by 1:24:23, a bigger margin than Sullivan's. Nicole Laughton was second in 20:26:22 and Lauren Puretz third in 20:32:27. The race's cruel moment came for local runner Devon Olson, second and 26 minutes down at mile 71, who fell around mile 89 and suffered a separated shoulder; Marathon Handbook reports that Rich and Mogavero called for medical help as they passed him, and Olson walked to the aid station under his own power.

The $20,000 winners' checks come from a $100,000 purse that Marathon Handbook calls the richest any United States 100-miler puts up, paying through seventh place in both races — for comparison, the UTMB winner collects 20,000 euros (about $22,900). "This is certainly unprecedented," Abramowitz said. "We'll have to plan. I don't know what this will look like." Both champions are Colorado residents. Marathon Handbook reports Sullivan, who also won July's High Lonesome, has ruled out racing again this year, while Allgood — a runner who once said she would never run 100 miles and has now done two in three months — has "a lot of things planned," including a February race and an international season opener.
