Need for Speed..

We took the dogs and my son up to the track at the local school this afternoon and I ended up running speed intervals.  I had never really done them before, so it was a new experience.  I was kind of surprised that the later ones were easier than the first few.  I think I am going to try to some each week.  It was a nice change of pace from my normal running.  Now I wonder what I will feel like running in the morning...  I’ll just go out and see how it feels...
