Today a bunch of us from the IE team ran the Woodinville Country Slough Run together. We signed up as "Team IE" and had 9 members - Sharon, Tony, Kellie, Rob, John, me, Jon, Scott, and Laurel. We all wore various IE team T-shirts:

While this was more of a "fun run" and less of a race - no chip timing, no starter gun - it was still my first actual 5K race. I finished in 22:43! That's 90th out of a field of 430. Quite a surprise, actually, because I usually tell myself I'm not very fast, and yet here I was running a 7:19 5K. I know 7 :19 pace isn't "fast" as 5K times go, but it was damn good for me, and it was easier than the last time I ran a fast 5k.
Update: The course was mismarked! They didn't use their certified course, and they're saying that that "overzealous" volunteers turned people around at the wrong marker. The actual distance ran was about 2.88 miles (according to Tony's GPS), not the full 3.1 miles. Had we ran a "real" 5K, my finish time would have been about 24:25. So I didn't set a PR, and my PR stays at 24:00 for a treadmill 5K. I don't know what a road 5K would be.
Race results: 90th of 430 overall, 68th of 198 for men, 14th for 50 for men 40-49. Not bad - I'm sure it's not as competitive as some races, but hey, I'm happy with it. BTW, the winner of the race was a 49 year old man with 15:48.
Rob and I stay together the whole run. Having a race partner was fun, and I'm sure our competitive streaks pushed us to finish faster than we would have racing alone. The whole team finished under 30 minutes.
I was really happy I didn't have any problems with my ankle (it's been having problems since the marathon). I had the plan of running 8:30 or so - training pace - to avoid injury, but as I started out I just felt great, no problems at all, and I just kept the pace up the whole race.
I'm going to put some 5K races into my Ironman Arizona training schedule. I'm sure I've got a sub 20 minute 5K in me.
