No way I'll be running along the sidewalk. When a Jamaican friend said how great it would be for me for my morning runs she was surprised when I said no way I'd run on that. Concrete is the worst surface for running. No give. I'll certainly use it when I walk to town or down the road on an errand or leisurely stroll. I'm out early enough for my runs that traffic isn't very busy. I've been fortunate to avoid injuries & plan to keep it that way, especially at my age, lol. I want to keep running as long as I can.
