Slacker Half Marathon, Relay & 4 Mile
The Slacker Half Marathon is the highest downhill half marathon in the country and possibly the highest downhill 4 Mile Run! Don't be misled by the name, this race is a challenge! With the distinction of being the highest downhill half marathon in the country, runners begin at 10,630 feet and continue traveling over a rolling hill descent to 8400 feet! The race ends in downtown Georgetown where runners are cheered on by adoring fans and showered with more freebies than they know what to do with!
