I don't have a problem with letting more people run the marathon trials, but it's a little late to be changing the standard. I know a number of women that would very likely have been able to run the 2:45, but instead chased the 2:43, blew up in the last few miles and came in between 2:45 and 2:47. That's a rough break for them.
This exact scenario happened. I've been coaching a woman for a few years who was borderline for 2:43. In her recent effort to achieve the standard, we set a race plan to target that time. Unfortunately, she wasn't able to quite hold that pace and finished 2:47. No doubt in my mind that she runs under 2:45 if we were more conservative. She previously ran 2:46.
At the end of the day, this isn't life and death. But it makes for a great story for those that make the Trials.
