The race went very well for me.  I predicted a 5-hour finish.  My marathoning career, you see, has been marked by diminishing returns.  A PR in my first marathon (4:25 at St. Louis, 2001) which was followed by increasingly slower times every year.  Some races have been easier than others, but I had reconciled myself to slower finishes.  
I figured 5:00 seemed do-able in relative comfort.  Last time I did Des Moines in 2002 it took me 4:45 and I really bonked at the end and had to walk a lot.
So I lined up behind the 5:oo pacer and followed him for 3 or 4 miles.  I then moved up to the 4:45 pacer, but she was just a few yards up the road.  So I picked it up a little to catch the 4:30 group (figuring they would be the Kenyans).  Catching that group at mile 8 or 9, I found the pace comfortable and reckoned I could run with them a while and drop back to the 5-hour group as the race wore on.  I was worried my right knee would act up, and it did at mile 9.  I fiddled with my stride and it never bothered me again.
This was my first experience with pacers.  But "Mr. 4:30" was right on the advertised at the halfway point. I found a 10:10 pace wasn't too bad, so I stuck it out.  It proved to be the right move.  The pacer was very encouraging and I didn't walk at all except through the aid stations.  I focused on staying just ahead of the pacer. And I did - my second half was faster than the first.  The last six miles were tough, but fun as I struggled to keep that diabolical pacer in sight.  I was very happy when I ran the 4 blocks in to the finish and broke the tape in 4:27:34.
I'm already thinking a 4:15 marathon is possible.  I'd like to tackle another trail ultra in the Spring or maybe run the Brew-to-Brew again, but I also want to prepare the randonneuring series.  Decisions, decisions!
