The Fittest Cities in America

"Now in its fifth year, the survey spans 30 U.S. cities and delivers up-to-date opinions from the American public on such categories as local attractions and family getaways, even holiday travel and the intelligence quotients of residents. Not surprisingly, the number of natural features, the quality of the cities' green spaces, walkability, and more were all factors in deciding which U.S. cities are in top form."

The top three fittest cities are Denver, Portland, and Austin.
