Two athletes just rewrote the history books at one of ultrarunning’s most grueling mountain races — and they did it in conditions that would make most people cancel a morning jog.
Ryan Sullivan and Hannah Allgood each claimed course records at the 2026 Run Rabbit Run 100 Mile in Steamboat Springs, Colorado, dominating their respective fields by over an hour while wave after wave of torrential storms hammered runners throughout the night.
Both champions pocketed a $20,000 first-place prize — but the real story is just how commanding their performances were in some of the most brutal conditions the race has ever seen.
And with the race organization announcing a jaw-dropping $100,000 first-place prize for 2027 and 2028, the stakes at Run Rabbit Run just got very, very real.

A Race Built for the Bold
The 2026 edition marked the race’s 14th year, and it pulled no punches from the very first step.
Starting at 6,695 feet above sea level in Steamboat Springs, the course immediately throws a 4,000-foot climb up Mount Werner at competitors — all within the first five miles. From there, runners tackle 101.5 miles of mountain terrain with over 20,000 feet of total elevation gain, a punishing second-half ascent up to Summit Lake, and a screaming six-mile descent back to the ski area finish.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
The Hare division — the elite competitive wave — set off at 1:00 p.m. on Friday, September 18. Rain arrived within hours and didn’t let up for most of the 12-hour overnight stretch, turning the course into something far more savage than any training run could prepare you for.
Sullivan Runs Away From Everyone — and Everything
Pre-race favorite Ryan Sullivan wasted no time asserting himself at the front of the men’s field.
Alongside fellow contender Jeff Mogavero and defending champion Jesse Rich, Sullivan crested Mount Werner in the opening hour. By the time the trio reached Fish Creek Falls at mile 17, Sullivan and Mogavero were already ahead of course record pace — clocking in at 2:39 elapsed.
The real separation came on the climb out of Fish Creek, just as the first thunderstorm rolled in. Sullivan built a three-minute lead by mile 24, stretched that to nine minutes at Summit Lake by mile 30, and never looked back. He led the final 75 miles of the race entirely alone.
Sullivan, who also won the High Lonesome 100 Mile earlier in the summer, arrived at the halfway point — Olympian Hall at mile 51 — in 7:46 elapsed time with a 15-minute cushion. Last year, he’d suffered badly in cold and rain at this same race, finishing fourth. This time, he showed up prepared for everything the Colorado night could throw at him.
Behind him, the men’s podium was anything but settled. Devon Olson — a local runner who had won the Cascade Crest 100 Mile earlier in the season — surged dramatically to second place by mile 71, closing to within 26 minutes of Sullivan. Then, cruelly, disaster struck. Olson fell and separated his shoulder near mile 89, forcing him out of the race. Rich and Mogavero, to their credit, sent medics back to assist him as they passed.

Sullivan crossed the finish line in 17:03:38, shattering Dave Stevens’ 2023 course record of 17:23. He even eclipsed Jason Schlarb’s legendary 17:15 effort from 2013 on the old course layout — a mark that had stood for over a decade.
Mogavero held off a late charge to finish second in 17:59:14 — the race’s ninth-fastest time ever. Rich, the defending champion, gutted out third place in 18:18:47, reportedly running portions of the dark mountain miles on a completely dead headlamp.
Allgood Obliterates the Women’s Record — in the Rain
Hannah Allgood ran a different kind of masterclass — one defined by patience, power, and an almost eerie consistency across 100-plus miles of mountain mayhem.
She shared the early lead with Isabella Poulos through the first climb up Mount Werner, but began pulling away on the descent to Fish Creek Falls. By Summit Lake at mile 30, Allgood had already built a 10-minute gap over second-place Sarah Humble, and was settling in for a long, dark, stormy night with a lead she would never relinquish.
The conditions during the overnight hours were relentless. Severe storms battered the high-altitude sections of the course, forcing several top women to make extended stops at aid stations simply to warm up enough to continue moving. Allgood pushed through it all, bundled head-to-toe in rain gear, over an hour ahead of her nearest competitor.
By mile 71, Allgood’s lead was untouchable. Behind her, the podium kept shifting — Humble eventually dropped from the race, and Nicole Laughton climbed to second place, while Lauren Puretz worked her way up through the field to claim third.

Allgood finished in 19:01:59, an astonishing 47 minutes faster than Emilie Mann’s 2024 course record. For context, Allgood had placed 10th at the 2026 Western States 100 just months earlier — and arrived in Steamboat Springs ready to make a very different kind of statement.
Laughton, a race veteran from sea-level Oklahoma who famously ran the course in a tutu, crossed the line in a personal best of 20:26:22 — a massive improvement over her fourth-place 21:52 finish in 2024. Puretz earned third in 20:32:27, while Poulos rounded out a strong podium in 21:04:26.
What’s Coming Next Could Change Everything
As if the records and the dramatic storylines weren’t enough, Run Rabbit Run dropped a bombshell the evening before this year’s race even started.
The race organization confirmed that the 2027 and 2028 editions will feature a $100,000 first-place prize for both the men’s and women’s winners. That announcement immediately changed the conversation around the sport — and put this Steamboat Springs race firmly on the radar of every elite ultrarunner on the planet.
For now, Sullivan and Allgood hold the records. The mountain has been conquered — at least until next year, when an entirely new field of hungry competitors will show up chasing six figures and a place in ultrarunning history.
