LONE PEAK VERTICAL KILOMETER

Friday, September 12, 2025 | 10:00 AM START

Potential Course Change in 2025

Due to ongoing construction at the tram summit station this summer, there’s a possibility we won’t be able to use the tram to transport runners down Lone Peak after the VK. If this happens, we’ll revert to the route we used in 2023, which climbs 2,750 vertical feet over 2 miles, but stops 700 ft below the summit. After finishing, runners will descend about one mile in distance and one thousand feet in elevation loss down a steep slope and then cat track to the Swiftcurrent Lift. From there they will download to the Big Sky Base area.

While the tram will operate during race weekend, it may not be approved to handle large public loads. This will not affect the 28K or 50K courses, as tram use will be limited to aid station staff. We hope to utilize the summit for the VK but won’t have confirmation until closer to race day.

Please only sign up for the VK if you are ok knowing you may not go to the summit this year. We’ll continue to communicate updates promptly as we learn more from Big Sky Resort.

The Rut VK is one of the most dramatic and challenging vertical races in the country. Runners will begin in the Big Sky Resort base area at an elevation of 7,534 ft and finish on the summit of Lone Peak at 11,166ft. It is ALL uphill gaining 3,632 ft. of elevation in 2.8 miles!

The first half of the course takes the most direct route to the summit heading up the ski runs known as Huntley Hollow and Calamity Jane to the top of the Swiftcurrent lift and the base of Bonecrusher Ridge.

The second half of the race along Bone Crusher and Alto Ridge to the summit is EXTREMELY STEEP AND TECHNICAL with sections of exposure and potential rockfall hazards. We will have safety personnel along the ridge keeping an eye out for runners and assessing any objective hazards, but the responsibility falls on you the race participant to be aware of your surroundings and other runners. This is a true mountain course and participants must be comfortable in steep and exposed terrain to participate in this event!

ADDITIONAL INFORMATION

Course Cut-offs

For the safety of our volunteers and Big Sky Resort employees on the mountain, we will have two cutoffs for the Lone Peak VK.

Cutoff #1: 1-hour cutoff at the top of the Swiftcurrent chair before runners head up onto Bone Crusher and Alto Ridge to the summit of Lone Peak. The top of the Swfitcurrent chair is approximately 1.7 miles from the start.
Cutoff #2: 90-minute cutoff for the top of Bone Crusher Ridge which is the first pitch of the alpine section.
The overall race course cutoff is 2.5 hours

Finish Line Aid Station

There will be an aid station with refreshments at the finish line staffed with energetic volunteers. The aid station is cupless so please pack a drinking vessel in your drop bag.

PRIZES

All VK finishers will receive a unique finishers award.
Awards for top three in each age group (Under 20, 20-29,30-39, 40-49, 50-59, 60-69, 70+)

Finally, we have a Jorts Division and will award custom denim vests to the fastest man, woman and non-binary athlete to summit lone peak in cutoff jeans! To enter into the jorts division, wear jorts. No denim print technical fabrics allowed!

Cash prizes for the top 3 overall men and women

First: $1000

Drop Bags

At packet pickup, we will provide you with a drop bag which you must use if you choose to have a drop bag at all. VK drop bags must be dropped off near the start line before 9:45 AM. We will take them up to the summit to greet you when you finish the VK. Having a layer for the top as well as a drinking vessel for our finish line cupless aid station is a great idea.

Course Markings (Green 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. 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. Course markings will be green pin flags.

Weather

Please be prepared for any type of weather. Though the 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.
