On point that has not been addressed in the OT Marathon, and needs to be, is the fact that it puts US runners at a disadvantage in the Marathon Majors scoring. (this may not be a huge deal now but within a year or two I see the Marathon Majors prise purse growing and deepening - Say 3 or 5 deep and $1 M to the winner)
The way it is shaping up it will take a good time/full effort for the top guys to make the US team (with several failing to qualify) given the field will now likely include: KK, Meb, Abdi, Culpepper, Shay, Sell, Browne and others. It looks like it will take sub 2:10 type of times make the team (or similar effort).
So this is a major effort for anyone. Given that most top marathoners only run 2 marathons per year all of their marathons are scoring efforts (4) under the Marathon Majors rules. Except for Americans who have run the trials. So they will have a major effort that can't earn them points in the Marathon Majors Championship.
There is only two ways around this as I see it. Hold the trials as part of either NYC, Boston or Chicago races or make the team be the top US performer at each of those three races (giving guys a potential of 3 shots to make the team).
