Kenya's Samuel Wanjiru, 21, broke more than an Olympic record with his 2:06:32 win; he crushed long–held conventional wisdom that marathon performance peaks among runners in their late 20s and early 30s. That conventional wisdom also took a beating when a 38–year–old mother with 10 marathons under her belt, Romania's Constantina Tomescu–Dita, won the women's event.If conventional wisdom is being upended, i.e. that the age bracket of late 20s-to-early 30s are no longer when runners do their best work, it seemed prudent to find out what the numbers themselves say. Hence I compiled the men's and women's ~2400 fastest marathon times (including repeat performances by individuals) to asses whether there is any temporal trends for fast runners. I chose an arbitrary cutoff point to compare: the 20th and 21st centuries.
