Just running a marathon not enough for you?
Claiming to be the highest paved-route marathon (8,150 feet) in the country, the Estes Park Marathon Sunday includes a half-marathon, the American Cancer Society Relay for Life, a 10K and a 5K on the same day. Children 6-12 can participate in a Fun Run Saturday in front of the Estes Park Town Hall. Race-day registration only for the 10K and 5K races, not the marathon or the half-marathon. Spectators can gather at the start and finish lines on the grounds of the Estes Park School campus, around Mary’s Lake, through downtown Estes Park, and near the Estes Park Visitors Center and along Dry Gulch Road. 970-586-8189;
