CLASSIC VERTICAL TRAIL RACES IN THE U.S.
What goes up … doesn’t always come back down. These hill climbs are brutal but reward you with great views from the top. These five vertical trail races each started as a simple test of who could get to the top of a local landmark the quickest. They are sure to give you burning quads and a spectacular view from the finish. Getting down is another issue… At the Loon Mountain Race, the six-and-a-half-mile course tests every type of ability. It starts out on cat track, changes to technical single track and then around the halfway point hits the first ski slope, with a grade between 15 and 20 percent. The most notorious section of the course is called “Upper Walking Boss,” a kilometer-long section that runs straight up a black diamond slope with a grade of 40 percent.
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..
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!
