Don't know how many of you guys follow cycling road racing, but I do know that a lot of you are interested in how fast one can ride. Today's Paris-Roubaix pro road race is probably the toughest one day race in the world. 160.5 miles long, 27 sections of horrible cobble stone road (totaling nearly 17 miles) and the winner road the race at just over 26 mph - about 6 hours 8 minutes!! Imagine 6 hours at 26 mph.
