Get mad, run well ?

SO have you ever had those runs where you are so mad about something that when you go running you find yourself flying along ? I have many times before and today was one of those days. I went down to the lakes for a easy run on the dirt cow track trails that run along the paved paths along the lakes. Well that lasted like all of 10 mins. then it was off to the races. It was a nice day for a run with temps in the mid 50's. I had my ipod a cranking and then the legs followed. I guess it all worked out since I felt good the whole way. I knocked out a solid 7 mile tempo run !! Funny how things can vary so much day to day.
