I waited in my car until right before the start, then went to the starting area and did some quick stretches. I met up with another racewalker that I know and we talked for a while. There were probably a little over 1,000 people at the race so it was a nice size (I always prefer smaller races). Then finally we were off and I started to warm up within seconds.
The course was fine, nothing too exciting or difficult. We skirted White Rock Lake for a while, then headed off into some of the neighborhoods around the lake, then back to the lake for the finish. There was only one "hill," and this being Dallas our hills are more like bumps for some of you.
I added a little kick for the finish and ended up finishing in 50:42, 18 seconds below my goal time of 51:00! My goal pace was 10:12 and I finished with a 10:08 pace, tying my PR pace for the 5k.

Unfortunately I am a knucklehead and I misread the Garmin screen. For most of the race I was ahead of pace but I thought I was behind (in the first half mile I was behind pace, naturally, and the feeling that I had to catch up was with me the whole race even though it is VERY easy to tell if you are ahead or behind). I kept trying harder and harder and kept seeing myself slipping behind, when actually I was pulling farther and farther ahead! I tend to speed up during races so I kept hoping I would speed up enough to catch that wily Virtual Partner. It was only until the last .75 miles that I realized I was ahead of pace! Then I felt AWESOME and kicked in to try and get a little faster.
According to the Garmin GPS I actually walked 5.17 miles, not 5, making my pace 9:48! I doubt the race was off by that much; it's probably a combination of the race course being a little long and how I ran the course. Dodging people, diverting to the side for water at aid stations, and how you take corners can all affect your distance. In any case, both paces were below my goal pace so I'm pleased. I hope everyone else racing today had similar good luck and a good time.
