He has to at least know about this thread by now. If there was a thread bashing me on here I'd certainly keep up on it and try to defend myself. In his case... well, it's not like he has much of a defense. Maybe he's trying to ignore it.
At this point do we assume that all his race times are BS? I can't imagine how difficult it would be to hit every 5k split at Boston. Those splits mostly make sense, too. Could he have possibly cheated at EVERY race?!
I can see some logic in - 'I don't think I'm in shape for a sub-3 this weekend. I better just play it safe and cheat.'
But shouldn't there be some weekends when he's feeling good and runs a respectable time for real?
