Painful Three Miles

I ran just 3.19 miles tonight, and my shins were KILLING me.  How could I go from being so comfortable running 9 miles on Saturday to being in such pain tonight?  Doesn’t make sense to me.  It was only in the mid 80’s, but I had worked 11 hours today.  Maybe that had something to do with it?

Friday is a rest day for me, and then Saturday I’ll be doing 10 miles.  Sure hope I’m back to normal.  Got an cold pack on my leg now.
