San Diego top marathon city, says Facebook
But it's not one of 10 fittest cities
Facebook has culled a list of cities dedicated to fitness. The calculation is based on user activity such as fitness-related status updates, gym check-ins, use of fitness apps, and fitness-related life events between January 1 and March 31 of this year. San Diego is the top city for marathons. But it doesn't make the list of the 10 fittest cities, which is headed by Virginia Beach and Colorado Springs.
