You will note that the other candidates, Bush and Edwards, show which marathon they have run and the exact times for each. As an aside, although I can't stand Edwards, his marathon times are pretty impressive.
Also, the qualifying times back in the seventies were under 3 hours. There is no way that a sub-3 hour marathoner would not remember running Boston for the first time. What a maroon!!
What a flat-out liar! Cambodia is one thing, but this is serious stuff.
< With the exception of Ronald Reagan, every president since the mid-'70s has been a runner. George W. ran a 3:44 marathon at Houston a decade ago. Kerry says he completed a Boston in the '70s but forgets his time (Question: Did he forget his qualifying time, too, or didn't he have to qualify?).
Even 2000 Democratic presidential candidate Al Gore finished a marathon once.
