Cosmo Catalano has created the Periodic Table of Professional Cycling for his cycling website, Cyclocosm.com.
The data lends itself surprisingly well to the periodic table format. Horizontal periods correspond closely to the prestige of each event, while vertical series indicate geographic location. Multi-day races are on the left hand side of the chart, one-day events on the right.
