5 on Tuesday around 8:45 or so?  Yoga yesterday, and then a regular run today--my knee was THROBBING just a mile or so in.  Like, insane pain.  I stopped at 2 miles and tried to sort of shake it out, then started again and I was dying.  Then Juliet came in with my new shoes--yay!  So I laced them up and started running--my knee felt better, but something with the brand-new cushioning made me feel like the bottom of my feet were on fire.  Really weird--I ran a mile and then stopped and re-laced them and ran another mile and it was better, but not much.  So I decided to take the time that I would normally spend on the last mile and just stretch and ice.  Sigh.
