The perimeter of Washington Park in Denver, CO is about 2.60 miles.
As the crow flies, it's only 54 miles to the Denver Capitol building. It is 81.66 miles according to MapQuest. Having gone to high school in Denver and lived in Breckenridge ROM 1970 to 1995, I have a clue. It's basically 90 miles. Nine miles from Breck to Frisco where you pick up I-70 and go east through Loveland Mtn. via the Eisenhower tunnel (which I worked on!)and then it's all downhill through clear creek canyon. As the crow flies, it's only 54 miles to the Denver Capitol building.
