Bicycle Racing

In spite of the fact that it violates the No Machines rule Bicycle Racing is a sport.

The best proof if the point I can think of was when the summer Olympics was in LA. An American cyclist was challenged by a German or French cyclist. In spite of the fact that the American had a high tech bike with the newest composite wheels and frame, he was unable to defeat the European with the more classic bike design.

So, at least at that time it was a test of the abilities of the man, not the machine. As long as that is still the factor tested then I would consider it a sport.
