What’s awe-inducing about Palin’s feat is that she accomplished it at 41 after having four children, while Ryan’s mark was set at 20 and Edwards’ best came at 30. There are only about 40 thousand women who were that fast or faster in 2011. (More comparisons: The average marathon time for a woman aged 40-44 in 2011 was 4:47:34. The average for a man aged 20-24 was 4:22:48.)
