Come join us for the highest DOWNHILL half marathon in the country and possibly the highest DOWNHILL 4 Mile Run!

Do not be misled by the name but this is the Slacker Half Marathon/4M Race! It is the highest downhill half marathon in the country---- beginning at 10,630 feet and traveling over a rolling hill descent to 8400 feet! The half marathon begins at Loveland Ski Area--BASIN and travels the first mile on dirt roads before joining a non-motorized paved bike path for five miles through a Forest Service area of wetlands and natural waterfalls on a trail built to sustain the weight of an ambulance!

The second 4.4 miles travel from Bakerville to Silver Plume along a paved frontage road with amazing views of the Continental Divide and mining remnants.

The last portion of the trail & the 4-Mile race travels from Silver Plume to Georgetown on a paved bike trail (and paved road) with scenic views of the Georgetown Loop Railroad and the largest Bighorn Sheep herd in the State!

The race ends in downtown Georgetown where there are more freebies than you know what to do with!

This is the SIXTEENTH annual Slacker Half Marathon/4M Race and we are offering three great races:

  • The Slacker Half Marathon
  • The Slacker Half Marathon 3-person Relay
  • The Slacker 4-Miler

This relay has a really great option! This year, one choice in the 3-person half marathon relay is you must have a physically challenged participant on your team to complete the second portion of the course (4.4 miles of newly paved road). The other option is the relay is open to everyone --just have 3 on a team!
