Saturday, June 22, 2019 • Georgetown, CO • Course Map
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 near-trail conditions through the first half of the race, which features five miles of forest area trails with plenty of scenic views of nearby wetlands and waterfalls.
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:
By alyeska2 in June 2013: “I’ve never seen so many runners finish a race with plantar fasciitis. Doing this much downhill running on pavement is torture on one’s plantar muscles and tendons. I counted 12 runners with symptoms of plantar fasciitis.”
By Melissa Hoskins in June 2011: “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!”
By Kimberly Anderson in October 2014: “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.”
By Briana Wilmott in October 2014: “For the most part I would say that it is 90% downhill. There are some areas that you will have to go uphill.”
