Marathon world record times have changed impressively in the past century. When Kenya's Patrick Makau Musyoki set the current men's world record at 2:03:18 in the Berlin Marathon 2011, he was more than half an hour faster than Italian long-distance runner Umberto Blasi in 1914.

This progression however, is minimal compared to how the women's world record has changed in the same period. Setting the current record in 2003, Paula Radcliffe was more than twice as fast as Marie-Louise Ledru of France in 1918. The average speed of the world record runner rose from a mere 4.62mph to 11.60mph, sharply narrowing the gap to the current men's record average speed of 12.71mph.This progression however, is minimal compared to how the women's world record has changed in the same period.
