When you add up the dozens of other long-distance cycling tours, and thousands of miles of training rides, he's put quite a toll on his body.

This bulging of the veins could be caused by a variety of factors, including genetics, but you can assume that a lifetime of riding a bike up and down mountains is not helping matters.

Hincapie, a long time teammate of Lance Armstrong, is currently in 40th place after six stages of the 2011 Tour. However, his current BMC Racing teammate, Cadel Evans, is in a virtual tie for the lead.
