Slacker Half Marathon

Billed by race organizers as the “highest downhill half marathon in the country,” the aptly named Slacker Half Marathon features a starting line at the lofty elevation of 10,630 feet above sea level and a running course that is entirely downhill, descending by the end of the race to 8,400 feet. The starting line lies at Colorado’s Loveland Ski Resort, and takes runners on a combination of dirt and paved roads, leading participants through beautiful wetlands, natural waterfalls, stunning views of the Continental Divide, and historic mining remnants. By the middle miles of the race, the course shifts to paved surfaces, with views of the Continental Divide and many mining areas, while the last few miles of the race take runners from Silver Plume to Georgetown along paved bike trails with views of the Georgetown Loop Railroad. The relay races are open to 3-person teams, and the 4-mile race takes place over the last four miles of the half marathon course. Here’s what past runners who’ve taken part in the race have to say about it, from comments left about the course on the old version of our site: “I told my I’m officially a slacker and for that I thank you! I thought the race was uniquely Colorado, which made for a wonderful experience. The volunteers and residents and businesses of Georgetown were incredibly welcoming. Thank you! For these reasons, and the fact that a mostly downhill at altitude is a real challenge and any athlete-at-heart will love!” “I LOVE Slacker! It was a bummer they’ve paved the forest road though, as running on the dirt trail was a favorite part of the race. Great race and day!” “I actually did this in June and loved it! First ever and unexpectedly got 2nd in my category It was all downhill though so probably not that great of an accomplishment haha.” “For the most part I would say that it is 90% downhill. There are some areas that you will have to go uphill.” Because of it’s unique, scenic course – we consider this race to be one of the best in the world.
