The Course

The Boss

Over the years our Loon Mountain Race has developed quite a following. The reputation as one of the country’s toughest mountain races is due in large part to the kilometer ascent of North Peak via the black diamond trail known as Upper Walking Boss. ‘The Boss’, as it’s affectionately known, is roughly a kilometer of grassy slope with angles that exceed a dizzying 40% grade!

Most Competitive Hillclimb

This race up Loon Mountain is an annual benchmark on one of the country’s most competitive trail running circuits. Among the most dastardly hill climb races in the country, the course of this five-miler has an average grade of 10 percent—but in some places it ascends at an unthinkable 40 percent—as it meanders upward on a combination of dirt trails, gravel service roads, and grassy ski slopes. -RW

Trail Runners Bucket List

Widely considered the New England Trail Running series’ most difficult event, the Loon Mountain Race in Lincoln, New Hampshire, packs a whopping 2,200+-vertical gain in just 6.6 miles. Racers literally run up a mountain—the average grade is 10 percent, with some sections as steep as 40 percent. The trail winds up the ski resort’s runs, including the black-diamond pitch Upper Walking Boss, before finishing at the top gondola station on Loon peak. -OM

Dirty Dozen – America’s Best Trail Races

Running 6.6 miles with over 3000 feet of vertical gain will definitely make you question the sanity of running up Loon Peak instead of skiing down it — especially on the black-diamond ski run portion, where racers navigate a 40-percent incline. Front-runners dance up the grass ski slopes, dirt trails and service roads like mountain goats.

The 15 Most Epic Trail Races Across The U.S.

This isn’t an ordinary trail race. It’s straight up Loon Mountain to the Summit Lodge at the top of the ski resort’s gondola. You’ll gain 2,200-plus vertical feet over a 6.6-mile course, which has been the site of the USATF Mountain Running Championships. While the average grade along the course is 10 percent, by far the hardest part is the ascent up the black diamond trail Upper Walking Boss – a staggering 40 percent incline!

The course will feature two fluid aid stations. The average temperature in July is 77F so make sure you run with fluids if you think you will need more than three hydration stops. We will provide fluids at the finish area and back at the Governor Adams Lodge.

Clothing Drop

You will be provided a “clothing drop” bag at registration which you may fill with dry/warm clothes for the finish. No coolers please. Once filled it is your responsibly to bring it to the Gondola loading area at the Base Lodge. There will be an area designated for these bags. They will be transported via the Gondola to the finish area.


The race will begin in Parking Area C and wind its way up to the cat track/service road to the right of Governor Adams Lodge and then travel along the service road heading up Loon Mountain before veering into the Nordic Ski trail network. After this relatively new section of course it follows a traditional combination of dirt trail, service roads, and ski trails to the Summit Lodge at the top of the Gondola. The course works its way over and up to the summit of North Peak via the infamous Upper Walking Boss black diamond trail. The race will finish in 2018 at the top of North Peak. The course averages approximately 14% grade with some sections of more than 40%!
