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 5.5 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. Besides featuring some of the best trail runners in the country, this race is also a women’s qualifier for the World Mountain Running Championships.
