Ryan Sullivan and Hannah Allgood both set course records at the 14th Run Rabbit Run 100 in Steamboat Springs, Colorado, which started at 1pm on Friday 18 September. Sullivan won the men's race in 17:03:38 and Allgood the women's in 19:01:59, each earning $20,000 for first place.
Conditions were severe. Rain arrived within hours of the start and lasted for most of the night, with thunderstorms in the high-altitude sections of a course that covers 101.5 miles with more than 20,000 feet of climbing from a start at 6,695 feet. Several leading women had to stop at aid stations to warm up.
Sullivan beat Dave Stevens' 17:23 from 2023, with Jeff Mogavero second in 17:59:14 and Jesse Rich third in 18:18:47. Devon Olson dropped after separating his shoulder near mile 89. In the women's race Allgood took roughly 47 minutes off the previous mark, with Nicole Laughton second in a personal best 20:26:22 and Lauren Puretz third in 20:32:27.
Off the course, the larger story may be financial. On the evening before the race, organisers announced that the winners of both the men's and women's races will receive $100,000 in 2027 and 2028, five times this year's first prize.
The announcement could reshape the sport's calendar. With a six-figure prize and a fast, runnable course now proven capable of record-setting times even in poor weather, Run Rabbit Run is positioned to attract deeper international fields, and to test the appetite for a genuinely professional 100-mile circuit.
