There’s not much to say about running on sidewalks other than that you should avoid it whenever possible. Sure, sidewalks are safer than roads with respect to cars, and maybe they don’t feel all that much different from asphalt. But they’re made from concrete and cement, which are some of the hardest surfaces around. When you figure that with every running step, you subject your body to a force equal to at least three times your body weight, it should be obvious that you want to do whatever you can to lower that impact shock.
Another good reason to avoid running on sidewalks is that they seldom provide an uninterrupted surface for long. You’re continually going up and down, up and down for driveways and curbs. This unevenness only adds to the pounding on your legs and is a good way to twist an ankle, too.
The only time it’s worth clinging to sidewalks is when you’re running in a busy section of a city. Even then, though, you’ll probably be making your way to a park, bike path, or other better option for the bulk of your run. Otherwise, try to spend as little time running on sidewalks as possible.
