Hanging with the leader pack

The nice weather is back so this weekend I went outside for a change.  I did one of my usual 6 mile loops.  On the way back, I noticed I was being passed by an inordinately large number of very fast runners.  Eventually I figured out I was on the early part of the course for the Frozen Half, the first long distance race of the year.  They were fast and on mile 1-2, while I am slow and on mile 4-5.  The true leader pack streaked by but I was able to hold it together after the first 20 runners or so and stay up with the second wave.  Decent weather but a bit icy if you are doing this for real.  Glad I could make the right turn by my apartment, catch my breath and jog it in.
