"knee"ding a day off

0 miles - I skipped a run today after going to a physical therapy speech on injury prevention tonight. Something about having trouble ascending and descending stairs and having to ice my left knee after runs leads me to believe that I need to give it a break for more than one day per week. Next step: apptmt with the PT dude to figure out how to be more kind to it. I'm also going to try to do some core strengthening and hip exercises as he thought that may be part of the problem as well. Secretly: I think it's either my butt that is always following me around or the extra 10 lbs I put on this past year or two. ;)
