4. Boston, MA
Boston may be the second runner's dream city on this list, but it's just as great for people looking to work out indoors. The city ranked third for gym access and getting to work by foot or bike. The food options leave much to be desired (it ranked 63rd out of 100), however, and it fell in the middle of the pack for outdoor activities.
