THE RUT 50K RACE
Sunday, September 15, 2024 | 6 AM START
There are sections of this course, including the ascent and traverse of Headwaters ridge, as well as the ascent of Bone crusher ridge towards the summit of Lone Peak, which are extremely steep and technical with sections of exposure and rockfall hazard. The result of a fall in these sections could be injury or death. The responsibility falls on the participant to have the skills to traverse these areas safely. Do not let the distance fool you. 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. If you are interested in the 50K but just don’t feel ready for the technical sections, we suggest checking out our new Rut 21K course.
*MANDATORY GEAR IS REQUIRED FOR ALL 50K & 28K RUT RUNNERS. LEARN MORE HERE

50K PLAN B - COURSE ALTERNATIVE IN THE EVENT OF EXTREME WEATHER
Due to the alpine and exposed nature of our 50K course, race organizers reserve the right to change the course in order to limit risk to rut runners. Here is a description of our 50K plan B course. It is a few miles shorter, has near 7,000 ft elevation gain, and does not access the Headwaters Ridge, or Lone Peak Summit.
September in Montana often brings the first winter snowstorms and blizzards to the high peaks. Or, a long Indian summer extending into September can also mean major electrical storms in alpine environments. The Rut 50km course (as planned) is on a high peak (11,160 feet), and on extremely exposed alpine terrain.
In the event that a major snowstorm or dangerous electrical storm hit Lone Peak on race day, the race directors reserve the right to alter the 50km course to keep runners safe. The Headwaters Ridge and Lone Peak sections of the original course are simply too exposed and technical to be safe for runners or safety personnel in the event of a major storm on race day. The “Plan B” course would remain approximately 50% true to the original course. The change would be that the course would stay off the high exposed ridgelines and not go to the summit of Lone Peak.
Plan B Course Description:
Though we haven’t GPS’d the thing, you can expect it to be a few miles shorter than 50K, and also have around 7,000 ft elevation gain. Giver or take a bit.
The first 12.1 miles of the alternative course would remain the same as the original course (Soul Hole-Tango-Challenger service road-Moonlight-Ullery’s Lake loop-Madison Connector-Madison Village-Moonlight Loop trail-Elkhorn trail).
Once reaching the top of the Elkhorn trail, where you intersect with the service road, head left and down the road. This road will connect back onto the Challenger service road. Head right following Fast Lane downhill and underneath the Challenger ski lift line back onto Big Sky Resort property.Go until the junction of Fast Lane and the Cairn’s Way single track mountain bike trail.Take a right at the junction onto the Cairns Way trail. Head uphill on Cairns Way trail until you connect onto the North Access dirt road.Continue uphill on this road until the junction with the Morning Star dirt road.Take a right onto Morning Star and continue uphill to the base of the Lone Peak tram and the Tram Dock Aid Station. Head back downhill along the Morning Star dirt road to the junction of Morning Star and the North Access double track.At the junction, turn right and head uphill on the North Access road.
Continue up the North Access road past the Swiftcurrent lift, heading south. You will now be running on the Duck Walk service road, heading south towards the top of Shedhorn ski lift. Once at the top of Shedhorn, you will do a steep off-trail descent through a rocky boulder field through Rockville Bowl, then hang a sharp right (again, off trail section – follow course markings!) and head back up a short steep climb (up the “screaming left” ski run).This will take you through rocky terrain to the top of the Dakota lift. Once you reach the top of Dakota, descend the Dakota road to the bottom of Dakota lift. You are now back on the original race course for the remainder of the race (see 50km detailed course description).

Wave Starts
To limit congestion on the course, the 50K will have wave starts. When participants sign up they share an estimated finishing time for their event. We then assign waves based on their estimated finishing time. We will send an email out to runners with their assigned wave. Also, runners’ waves will be on the back of their bib. Runners must start in their assigned wave. Help us in limiting congestion on the trails. Thank you!
*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.
Drop Bags at Swiftcurrent Aid Station
All 50K runners receive a Rut drop bag at check-in that runners can use for their Swiftcurrent Aid Station. Drop bags are to be dropped off before the race near the start line and they will be at the aid station ready for you when you come through. You will mark your bag with your number and we have a system at the aid station to see your number and have your drop bag ready for you on arrival. Drop bags that have been used will be back in the base area in the afternoon and ready for pick up near the finish line.
Crewing/Spectating
There will be no crewing of runners 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 the nearest aid station captain if you drop out of the race.
50K Course Markings (Orange Pin Flags)
This is not an orienteering race. The race organizers will do everything they can to have the course marked well for race participants on the day of the event. Runners must follow trail marking and not cut switchbacks. 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. The Rut 50K will be marked with orange pin flags with a Rut Logo on them.
Course Reconnaissance
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. Please check out Big Sky Resorts’ summer trails map to see what trails allow running and hiking before heading up to the resort.
Weather
Please be prepared for any type of weather. Though the weather in Big Sky is relatively mild and stable in September, 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 50K Plan B course, which will not take race participants into exposed alpine terrain, should extreme weather exist on race day.
