Paul Ryan claimed in an interview that he ran a marathon under 3 hours. Then he got called on it (by, among others, his own family).
One does not run a 4:01:25 marathon and then remember having run it under 3 hours. I know my times in every significant race I’ve run, and the vast majority of endurance athletes are just as neurotic about it as I am. Even accounting for 20-some years of memory lapse (he ran the race when he was 20), that’s simply not the kind of thing someone forgets.
I suspect this statement was evidence of someone completely at ease with lying.
