THAT wasn't the plan!

Today the plan was to do 10 miles in the hills.  I did about 2.  Something went horribly wrong and my calves were cramping.  Cramping HARD!  It was like duel charlie horses.  I knew enough to realize that it meant something was wrong.  I don't know what, but something.  I decided not to push it but instead listen.  I hobbled home and will attempt this long run tomorrow instead.  Today is about icing, stretching, hydrating and getting ready to try again.
