My first running race in 19 years. My first race in almost that much time that I actually cared about the outcome going into it.
The night before I was lying in bed thinking about what it was like to race when I was competitive. I was thinking that it would be very different running for time in the middle of a mass of people as opposed to racing for position. As it turned out a guy caught me at about 10 1/2 miles and I got to race almost all the last 3 miles. It really made the race fun and changed the whole experience.
