Weldon, Robert,
I am a coach, 7 out of my 9 guys PRd, I had 5 guys who work or go to school full time (45-60 hour work weeks) in the top 55 American men (top 85 overall), 3 in the 2:20s (2 of which had never run a marathon before), I had less "blow ups" then the Hanson's, AND I ran the race, unlike Kevin.
I think that puts me in a better position then Mr. Hanson to comment on the race, and certainly in a better position then you. But that doesn't matter so much, because you're taking Kevin's quote out of context, and he was pretty much spot on.
The discussion of this thread was that the weather was a factor on times. To say otherwise is completely ridiculous. Could you PR, yeah... especially if your PR was soft, you came in very fit, ran smart, stayed hydrated, had some luck, and perhaps had trained in the heat all summer.
Was it ideal? No. Look at the top times, the times across the board for that matter. Growing a pair has nothing to do with running while dehydrated, with heat stroke, etc. If anything, growing a pair with those conditions can be fatal, or seriously detrimental to your health. I would rather my guys not try and be macho and finish a race that could harm their development, recovery, etc., then "grow a pair" and suck up the consequences.
Again, this is coming from someone who had a successful marathon as an athlete and a coach (though I wish I was 45 stinking seconds faster so I could have a 2:39 PR... Oh well).
Bottom line, as Kevin mentioned, the weather was 10 degrees warmer then ideal. For those in the 2:30+ range, it was likely 15 degrees warmer then ideal. That CAN make a big difference in your time, and that is all anyone is saying.
People said NYC was windy last year... I didn't even really notice it. People say it was warm in Chicago this year... but it didn't really bother me that much. That doesn't mean commenting on it, saying it could have been a faster day, etc means that you need to grow a pair. You rarely get ideal conditions, but you hope that you do. I don't see what is wrong with that. Could it have been worse? Absolutely. My worst fear was not that it would get to 80, but that it would be 40, rainy and windy. For me personally, after training in the heat all summer, that would have been much worse.
