I am supposed to be doing my 3rd run tonight with my running buddy but I have immense back pain and I still have work this evening. I wonder if I will be getting this pain after every run as it is from an old injury.. How do you cope with injuries? I don't want to end up giving up!! Is it wise to go along with my buddy and do walking instead of running? I don't want to hold him back either! I have also been suffering with pain in my thighs.. Has anyone had this and is there a stretch before or after that will help ease it?
