Slacker Half Marathon
Slacker Half Marathon is a hilly half marathon in Georgetown, USA, held each June. A largely downhill half marathon from the base of Loveland Ski Area to Georgetown, on a mix of dirt and paved roads past wetlands, waterfalls and views of the Continental Divide. Late June at this altitude starts cold, around 0 to 6°C at dawn, and warms to about 15 to 22°C by the finish, with afternoon storms possible. Georgetown's hills change the plan itself: expect hill repetitions and long runs that rehearse the course's shape.
