Well a marathon can be walked also Harvey. It doesn't have to be run on and pound those arthritic knees. I plan to walk a marathon next year since I know my knees and back can't take the pounding of running. I have a patient who walks marathons in 6 hours.I don't care about my time or getting a ribon.I just want to check it off my list. I wish I had done it while I was in Whitney hiking shape which was up until last year.
My thoughts having trained like I was training to hike Whitney and walk a marathon would say climbing Whitney is way tougher due to the altitude.
