I still want to run marathons

I still have the groin pull that was self inflicted on 8/11.  It seems the more I lay around the more I hurt.  My whole body hurts and I haven't did much of anything.  I had to start moving, even if it is causing me discomfort.  I don't think it will hurt anymore from walking on the treadmill than it does laying around.  I did a very slow walk yesterday for 25 minutes and went 1.10 miles.  It was uncomfortable during the whole walk.  I hurt today more than yesterday but my mental attitude is so much better.  So I will walk again today for a mile or so.  I will get this figured out soon.  I still want to run marathons        Just Run
