Honolulu ranks as seventh best urban area for walking, according to a study commissioned by Prevention magazine and the American Podiatric Medical Association.

The report placed Honolulu just behind Cambridge (Mass.), New York, Ann Arbor (Mich.), Chicago, Washington, D.C., and San Francisco. The study surveyed more than 500 of the most populated cities in the nation against 14 walking criteria, including the percentage of people who walk to work, number of parks per square mile, use of mass transit, and percentage of adults who walk for fitness.

The worst walking cities were rated as: Oklahoma City, North Las Vegas, and Gadsden, Ala. Prevention and the APMA annually team up to measure the walkability of America's cities. The report sponsors said walking is the most popular form of exercise with 87.5 percent of Americans walking for fitness.
