Another View: Age Progression of sub-10 Second 100m (Men)
The graph above (work in progress) shows the same data on male sprinters who ran sub-10 seconds 100m as I showed last week. This time, I have connected the dots representing the same individual. Every once in a while the lines are do not have a slope of one, because birthdays and track evens don't always align neatly. The various blue dots show runners who did not break 10 seconds in successive years. The source is IAAF.
