Slacker Half Marathon-Relay-4-Mile Races

Get ready to redefine "slacking" at the Slacker Half Marathon-Relay-4-Mile Races, an exhilarating downhill adventure set for June 20, 2026, in picturesque Georgetown, Colorado. This iconic event offers distances of 13.1 miles and 4 miles, including a relay option, promising a truly unique high-altitude experience. Renowned as the country's highest downhill half marathon, the race is a favorite for those chasing a personal record amidst some of the most spectacular scenery the Rocky Mountains have to offer.

The journey begins at the Loveland Ski Area, perched at an impressive elevation of 10,630 feet, and descends a remarkable 2,200 feet to the finish line in historic Georgetown at 8,400 feet. The course presents a thrilling mix of dirt and paved roads, guiding participants through enchanting wetlands, past natural waterfalls, and offering breathtaking views of the Continental Divide. Runners will also pass remnants of historic mining sites and enjoy scenic views of the Georgetown Loop Railroad in the later miles. While the downhill gradient is a significant advantage for speed, don't let the name fool you; the continuous descent can be punishing on the quads, and the high altitude adds an extra layer of challenge, making it a test for even seasoned runners. Typical race day conditions in late June bring highs around 75°F and lows around 44°F, with a low chance of precipitation.

Runners consistently praise the Slacker Half Marathon for its gorgeous course and well-organized atmosphere, featuring plenty of aid stations stocked with water and Gatorade every few miles. The finish line in charming Georgetown transforms into a vibrant post-race party, complete with freebies, locally crafted beer, food, and entertainment, creating a fantastic celebratory vibe.
