Oops. In a radio interview last week, Republican vice-presidential nominee Paul Ryan claimed his fastest marathon time was under three hours. The running world was skeptical. It turns out that Ryan ran Grandma's Marathon in Duluth, Minn., in 1990, when he was 20 years old. His time? 4:01:25. Making things even more awkward for the Ryan camp is the fact that this is the only marathon he's ever run. By Saturday night, Ryan admitted he misspoke when said he had run a marathon in "two hours and 50-something minutes."
