To hit an A goal, everything has to be perfect on race day, assuming your training puts you in reach of that goal anyway. An A goal is an all out performance, and you need perfect conditions for that - health wise, head wise, weather wise, people around you wise etc.
Not having been there, it seems to me that heat was a major factor for almost everyone. To do well, you need cold weather.
I have had a DNF at the Paris Marathon (last year) due to illness. You brush it off and move on. Sure it sucks to put in all that training effort, not to mention the cost of the trip from the USA, but I don't spend a whole lot of time mourning things that I cannot control. I do spend a whole lot of time pissed at myself when it's my fault I missed the goal (going out to fast at the Steamtown Marathon).
I firmly believe that if you are attempting a new pb, or an aggressive A goal, it can only mean that you have trained appropriately - and that's a huge effort. You should still hold you head high knowing that you did all you could do, and that the vast majority of the populace did not even have the temerity to try.
