The old joints complain that's for sure. Three miles a day and five on Sunday is 22 miles a week. The minimum for running a marathon is believed to be 35 miles a week. I mean running, not this walking the last five miles lazy sh*t that some people do. Its cold outside and I do not like the cold but I use gloves and a head band for my ears. I used to use a stop watch and time my runs but now I am so slow that the old ladies with the walkers pass me on the uphill sections. I hate lifting weights but that is about the only way I will get my bowshooting muscles back.
