Everyday I see runners taking to the sidewalks. Truth be told, that's one of the worst places to run. Concrete is a very unforgiving surface and not a place to run if you're seeking longevity. Rule of thumb is grass, asphalt, sidewalks. I've been running for more than thirty years injury free. Almost all of my runs have been on grass or asphalt (roads). Sidewalks were avoided as if they were quicksand. Ok, I know there are times when sidewalks can't be avoided. In those cases, wear your well cushioned shoes and limit your distance. Better still, run early in the morning. The roads are clear. And that's how you Keep It Moving.
See you on the road, right!
