THE RUT 28K RACE
Saturday, September 16, 2023
MANDATORY GEAR REQUIRED FOR ALL 50K & 28K RUT RUNNERS. LEARN MORE HERE
WARNING: This is not your normal 28K!
There are sections of this course, including the ascent and traverse of Headwaters ridge, as well as the ascent and descent of Lone Peak, which are EXTREMELY STEEP & TECHNICAL with sections of exposure and potential rockfall hazard. The result of a fall in these sections could be injury or death. We will have safety personnel along these sections, but the responsibility falls on the participant to have the skills to traverse these areas safely. This is a true mountain course so please treat it with the respect it deserves! We strongly encourage you to become familiar with the course terrain before registering for this event.
Aid Stations & Cut-off Times (We are a cupless event)
There are 3 fully stocked aid stations & 1 water only station located along the 28K course. Each aid station will be supplied with water, Skratch Labs goodies, sweet and salty snacks, first aid, and energetic volunteers!

28K PLAN B - COURSE ALTERNATIVE IN THE EVENT OF EXTREME WEATHER
Due to the alpine and exposed nature of our 28K course, race organizers reserve the right to change the course in order to limit risk to Rut Runners in the event of severe weather. Here is a map of the Plan B 28K Course.
We will have $4500 in cash prizes for the top 10 overall men and women of the 28K!
- First: $1000 (USD)
- Second: $500 (USD)
- Third: $350 (USD)
- Fourth: $250 (USD)
- Fifth: $150 (USD)
All 28K finishers will receive a unique finishers award.
Also, we will have unique and fun handmade awards for top three overall men and women as well as top 3 in each age group. (20-29,30-39, 40-49, 50-59, 60+)
When participants signed up for the 2022 Rut they shared an estimated finishing time for their event. We then assigned waves based on their estimated finishing time and have sent an email out with wave assignments. There will be 5 waves separated by 5 minutes each for the 28K in 2022. Runners’ waves will be on the back of their bib and runners must start in their assigned wave. Help us in limiting congestion on the trails. Thank you!
Lastly, overall awards will be based on the time from when the gun goes off with the first wave. Age group awards will be based on chip timing.
There are no drop bags for the 28K.
Crewing of runners is not allowed. You are, however, highly encouraged to get out on the course and see your runners as much as possible and cheer for them!
Dropping out: You must inform a race official if you drop out of the race.
28K Course Markings (Blue Pin Flags & Tape)
This is not an orienteering race. The race organizers will do everything they can to have the course marked well for race participants the day of the event. Off-trail sections of the course will be marked in a way that race participants should be able to see from each course marking to the next to help guide them along the course. During the on trail sections of the course, runners must stay on the trail. No switchback cutting! The 28K will be marked with blue flagging and tape.
We welcome you to check out the Rut course prior to the event, but please be aware that you cannot go on the downhill mountain biking trails other than race day. It is unsafe to do so. Also, in 2022 the Bonecrusher ridge climb to the summit will be closed due to tram construction. Please check out Big Sky Resorts’ summer trails map to see what trails allow running and hiking before heading up to the resort.
Please be prepared for any type of weather. Though weather in Big Sky is relatively mild and stable in mid-September historically, we are still in the mountains and conditions can quickly change. This is a challenging run on challenging terrain and the race organizers reserve the right to stop the race at any time, should they deem the course unsafe due to weather. The race organizers will have a 28K Plan B course, which will not take race participants into exposed alpine terrain, should extreme weather exist on race day.
