Sullivan and Allgood smash Run Rabbit Run 100 course records

Ryan Sullivan and Hannah Allgood both set course records at the Run Rabbit Run 100 Mile in Steamboat Springs, Colorado, on a night of torrential rain. Sullivan ran 17:03:38, Allgood ran 19:01:59, and both won by more than an hour.

Jeff Mogavero was second in the men's race in 17:59:14, with Jesse Rich third in 18:18:47. Nicole Laughton took second in the women's race in 20:26:22 and Lauren Puretz was third in 20:32:27, per iRunFar's results.

The weather was the story behind the story

The competitive Hare division started at 1 p.m. Mountain time on Friday, September 18. Rain began a few hours in and kept going for most of the 12-hour overnight section, often heavy. iRunFar says the placings behind the leaders stayed unsettled deep into the race as storms rolled through.

Sullivan had reason to be ready for it. He finished fourth here last year after suffering in the cold and rain, and iRunFar reports he was better geared for the overnight hours this time. He also won the High Lonesome 100 Mile earlier this summer.

How the men's race broke open

Mogavero and Sullivan led up the opening 4,000-foot climb over five miles to the top of Mount Werner, hitting it in 1:04 with defending champion Rich in tow. The two leaders reached Fish Creek Falls at about mile 17 in 2:39, already ahead of course record pace.

Sullivan took the lead climbing out of Fish Creek, had three minutes at mile 24 and nine minutes by Summit Lake at mile 30 in 4:46 elapsed. iRunFar says he was unchallenged from there.

This was the 14th edition of the race, over 101.5 miles with 20,391 feet of climbing, from a 6,695-foot start to a 10,600-foot high point. The purse paid $20,000, $8,500 and $5,000 to each podium and went seven deep. The night before the race, organizers announced a $100,000 first-place prize for 2027 and 2028, which iRunFar says pulled extra attention onto this year's edition.
