About the Slacker Half Marathon-Relay-4-Mile Races
The course runs almost entirely downhill, dropping from the base of a ski area to a historic mountain town. Along the way it moves through wetlands and past natural waterfalls, with long views of the Continental Divide and the occasional remnant of old mining country. The surface switches between dirt and pavement, so the footing changes as you go.
The finish is at City Park, where there is locally brewed beer, post-race food, and live entertainment. Packet pickup details and parking are on the race website, and there is no race-day registration, so sort that out beforehand.
