Given the two half times that are very likely legitimate, 1:32 and 1:28, my prediction is for a 3:12 finish. The other possibility is that he tries to prove to the running community that he really is a 2:55 runner and goes out too hard and DNF's before 20 miles.
Again, though, as I said before for an aging master a 3:12 isn't a bad time. By no means is it competitive in anything other than a local race, but at the same time it isn't anything to hang your head over. It demonstrates a commitment to this sport and an intelligent approach to training. If you don't believe me, wait until your 50 and see what it takes to keep yourself healthy and still post a decent time on race day.
I still can't fathom why he wouldn't prefer a legitimate 3:15ish time over a kipped 2:55. For the non-running crowd, who he's trying to impress, there's no difference between the two. Anything under five or six hours is going to seem like an amazing effort.
Oh, yeah. Put me down for one of those "where your dreams become reality" singlets.
