THE DREAM
A 50-mile and 100-mile course run through the mountains and fall foliage of the Routt National Forest in northern Colorado.
The 100-mile course also passes over Emerald Mountain.
Picture the course in advance
and find the pace that fits you.
Streets lined with cheers, runners all around.
You'll be part of that scene.
Take it slow with the finish still in you,
and meet the city all over again.
From the joy of finishing to the tough moments — read what runners wrote themselves.
“Well team, we made it to 98.”In their first 100-miler, this runner battled heavy snow, hail and cold, and on the final descent, ankle pain, a dropping body temperature and route confusion hit all at once and they stopped. They'd made it 98 miles, and say they'd never have gotten that far without pacer and their crew.
“First, this was the perfect course for my first 100.”In their first 100-mile race, the runner climbed the steep opening section slowly and enjoyed the descent through aspen woods in their autumn colors. At night, they struggled over steep climbs, and the altitude made it difficult to eat. The runner found their strength again in the latter stages and finished in 27 hours 28 minutes, satisfied with the support from the aid stations and volunteers.
“I enjoyed the strategic calculation involved to complete this race.”This runner finished the Tortoise Division in 29 hours 42 minutes 1 second and said the course was tougher than expected, so strategy mattered. Highlights: the spectators who rode the gondola to the top of Mount Werner to cheer, and their husband finishing his first 100-miler.
“My friend Kyle and I signed up and completed the race together as our first 100 miler.”A first-time 100-mile runner documented the long climbs, technical descents, rain and sleet, and aid-station experience at the Steamboat Springs course.
“2nd woman - 15th finisher - 9 hours 20 minutes.”In the runner's first 50-mile race, they made it through the steep climbs in the first 6 miles and approximately 9,000 feet of total elevation gain. The scenery of the course, aid stations, and the volunteers' encouragement were impressive, and after enduring difficult sections in the second half, the runner picked up the pace again on the descents. The runner finished in 9 hours 20 minutes, placing 2nd among the women and 15th overall.
“But even when I wasn’t moving with energy, I was still moving.”In the 100-mile Tortoise category, the runner struggled with the elevation, cold at night, and a lack of energy in the latter stages. With help from a pacer, the runner ran the final long descent and finished third in the category.

RACE WEEK
Know the course and time limit, and race day comes into focus.
From the 2026 editionThe 2026 Run Rabbit Run 50-mile starts on September 19 at 06:00 and runs until 21:00 (15 hours). The 100-mile race runs until 19:00 for Hares and 21:00 for Tortoises, with age-based early starts available.
We have not confirmed the start line coordinates yet.
Cutoff
Tortoise: 36 hours (Saturday at 9:00 p.m.); Hare: 30 hours (7:00 p.m.); Tortoise participants aged 60 and over for men and 50 and over for women receive an early start with a 38-hour cutoff
The 100-mile course of the Run Rabbit Run begins at the base of the Steamboat Springs ski area,
passes Buffalo Pass and Emerald Mountain, and passes through downtown Steamboat Springs several times.
The course centers on fall mountain trails in Routt National Forest, and Buffalo Pass sits at 10,300 feet above sea level.
Because it passes through town between mountain sections, it has a different rhythm from a completely remote course.
The cumulative elevation gain of this course is approximately 22,000 feet.
With 100 miles of high points and repeated climbs and descents, you'll have to manage the climb as well as the distance.
In the 2026 race, the 100-mile participants were divided into Tortoise and Hare groups and started at 9 a.m. and 1 p.m. on Friday, respectively.
The results have been recorded since 2007, consistently showing the character of mountain ultras.

Pick up your bib, check your wave.
So on race morning, you can just run.
The 100-mile and 50-mile races take place over two days, Sep 18 (Fri)~Sep 19 (Sat), with the 50-mile starting at Steamboat Ski Resort at 06:00 on Saturday.
Packet pickup also serves as the pre-race briefing by the race director; check the official website for the specific time and location.
Steamboat Springs Ski Area base (Steamboat Resort), elevation ~6,900 ft, Steamboat Springs, CO
No public transit station at the ski base cited on official site; 100-mile starts Friday Sept 18, 2026; 50-mile starts Saturday Sept 19, 2026, both at the ski area base. Official site (runrabbitrunsteamboat.com) confirms dates and start/finish at the ski area but does not detail shuttle, parking, or road closures.
Steamboat Springs Ski Area base (same as start — out-and-back/loop course design)
No public transit noted on official site. Post-race party at the finish line starting around noon.
No dedicated fare card is needed here: Steamboat Springs Transit, the local city bus, is fare-free for all riders. It does not, however, serve the remote race trailhead, so car or event shuttle access is required on race day.
Your start time, fuel and bag drop.
Know them ahead and the run feels easier.
Mid-September is when fall colors appear in the Routt National Forest.
However, since the course rises to 10,300 feet above sea level and the cumulative elevation gain is about 22,000 feet,
plan your layers around the altitude and mountain sections rather than dressing as you would for a long run on flat ground.
Since there are long climbs and descents repeated for 100 miles,
you need to plan how to manage your effort and fueling on the climbs, rather than focusing on early speed.
The race starts at Steamboat Springs Ski Area Base.
When choosing accommodation, prioritize easy access to the start at the ski area base over sightseeing in town,
and plan your travel around the race start time during race week.
Check the packet pickup time and location in the 2027 participant information and then organize your route in advance to avoid confusion about the race start and pickup locations.
Times are local to Steamboat Springs. Check the latest official information before the race.
