Before the race I was a little concerned about how I would feel running it 20 weeks pregnant. My longest runs of late have only been ~8 miles. So, I decided to take it very easy the first 7 miles, running (I think) around a 9:30 to 9:45 pace. In order to just relax and enjoy the scenery, I didn't wear my Garmin. I asked some runners around me for the time at the 7 mile mark, so, I think that is about where I sat.
Since I was feeling so good, I decided to have a little fun with the second half of the race. I gradually sped up over the next few miles and let myself comfortably push it the last 4 miles or so. Man, did it feel good to go a little faster for a change. I made sure my breathing was still easy, etc, but definitely had some fun out there.
One thing this event did really well was stagger the full/half marathon starts. The full marathon (which covers the half marathon course +6 more miles out and back on the same trail) started 1.5 hours before the half marathon. Not only did this ensure that the trail wasn't too crowded at any given time (it was either sidewalks or a narrow bike path) but had the added bonus of some speedy (I consider 3:30 a speedy marathon time =)) marathoners finishing around the same time I did. Since I had sped up, I was keeping pace with some of the marathoners toward the end (they were likely going around 8:00/mile). This made the finish more fun and exciting! I was shocked, and pleased, when I came in at 1:58 feeling so good! While that's not a 'fast' time for me, it's ~9 minutes faster then the half I ran 10 weeks ago. I'll take it!
After having that much fun, I really hope my running continues to go well. If it does, perhaps I'll try another half marathon at 27 weeks. It's one of my favorites (Pasadena) and I was really sad when I thought I'd have to miss it this year, since this is likely the last year I could do it (we're moving out of CA soon). Maybe I'll get lucky and make it to that one too =)
