knee stuff

didn't know what to call this one..cause..no i have not run......went to the doc who sent me to a p.t....who is a runner.....and he told me what to do..which is.....what i am doing............thanks to all the I T experts.....everything you said was correct....and sooooo now...i have to keep the milage low.....and he thinks that i can still do the marathon if i will let it rest for a while.....just keep the cardio stuff up....which means that hateful elliptical.............guess it is time to put something new on the mp3...and get to it...........................................over and out.....good buddies.......hope your days are good.....patti g.
