Two ultrarunning athletes just rewrote the history books at one of Colorado’s most grueling mountain races — and they did it in absolutely brutal conditions.
Ryan Sullivan and Hannah Allgood each claimed victory at the 2026 Run Rabbit Run 100 Mile in Steamboat Springs, Colorado, smashing course records that had stood for years.
What makes these performances even more jaw-dropping is the backdrop — wave after wave of violent storms battered runners across 101.5 miles of high-altitude mountain terrain throughout the entire race.
And with a jaw-dropping $100,000 first-place prize just announced for 2027, the spotlight on this race has never burned brighter.

Records Shattered, Prize Money Banked
Sullivan crossed the finish line in 17:03:38, obliterating the previous men’s course record of 17:23 set by Dave Stevens back in 2023.
He was even faster than Jason Schlarb’s legendary 17:15 finish from 2013 on the old course. Both records, gone.

- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
On the women’s side, Allgood finished in 19:01:59 — a stunning 47 minutes faster than Emilie Mann’s 2024 course record. Both champions pocketed a $20,000 first-place prize and ran away from the field by more than an hour.
The race organization had dropped a bombshell the night before the event, announcing a $100,000 first-place prize for both 2027 and 2028 — instantly elevating the stakes for everyone on that start line.
The Course: A Beast at Any Speed
Run Rabbit Run is no ordinary hundred-miler. Starting at 6,695 feet above sea level, the course punches up to a 10,600-foot high point with a relentless 20,391 feet of total elevation gain.
Runners face a 4,000-foot climb right out of the gate up Mount Werner, followed by a brutal ascent up Fish Creek, and then a sustained 3,500-foot grind to Summit Lake in the second half. Add torrential overnight rain, crackling thunderstorms, and freezing high-altitude temperatures, and the 2026 edition became something truly savage.
Sullivan’s Dominant Solo Mission
Sullivan, who also won the High Lonesome 100 Mile earlier this summer, took command early and never looked back. He and pre-race favorite Jeff Mogavero led together through the opening miles, reaching the Fish Creek Falls checkpoint ahead of course record pace at just 2:39 elapsed.
By mile 30 at Summit Lake, Sullivan had opened a nine-minute gap. From that point forward, he was essentially racing alone — leading for nearly the final 75 miles of the event.

Last year, Sullivan struggled badly in cold and rain when he finished fourth. This time, he came prepared. He even skipped the Long Lake aid station at mile 89 entirely, refusing to lose a single second.
The drama behind him was something else entirely. Local runner Devon Olson surged into second by mile 71, closing to within 26 minutes of Sullivan — before a devastating fall separated his shoulder at mile 89 and forced him out of the race. Defending champion Jesse Rich and Mogavero reportedly sent medics back to assist Olson as they passed, a moment of humanity in the middle of a very hard night.
Mogavero ultimately held on for second in 17:59:14, while Rich — running part of the night miles on a dead headlamp — finished third in 18:18:47.
Allgood Storms Through the Night Untouchable
Hannah Allgood, who placed tenth at the 2026 Western States 100 in June, ran an entirely different kind of race — one defined by calm, controlled dominance through absolute chaos.
She and Isabella Poulos led together through the opening climb, but Allgood began pulling clear on the descent to Fish Creek. By Summit Lake at mile 30, she was already setting the tone with 5:32 elapsed — heading into a long, dark, rainy night with a growing cushion.
As severe storms hammered the high country in the overnight hours, several top women were forced to make unplanned stops at aid stations just to warm up. Allgood, wrapped head-to-toe in rain gear, just kept moving.

By the time dawn broke — bringing more rain instead of relief — she was over an hour clear of everyone behind her.
Second place came down to a quietly remarkable run from Nicole Laughton, a race veteran from sea-level Oklahoma who finished in 20:26:22 — wearing a tutu. She’d placed fourth in 2024 and improved her time by nearly an hour and a half. Lauren Puretz continued climbing through the field all day to claim third in 20:32:27, and Poulos rounded out the top four in 21:04:26.
What’s Next for These Record Breakers
Sullivan now holds two major 100-mile wins in a single summer season — a remarkable stretch of performance at the highest level of the sport.
Allgood’s victory, coming on the heels of a strong Western States result, signals she is firmly in the conversation as one of ultrarunning’s most dangerous competitors heading into 2027.
And with a $100,000 prize now waiting at the finish line next September, the 2027 Run Rabbit Run field is going to be absolutely stacked. The mountain just got a whole lot more interesting.
