Today is the first rest day of the 2002 Tour de France (there is another scheduled for next Monday). If you are riding a bicycle 3300 kilometers (around 2050miles) in three weeks, you might want to rest a day or so. But since the real race begins in the Pyrenees later this week and since so many Americans have no idea what is going on over there–just that Lance Armstrong, a Texas boy–is the favorite, I thought I’d skip my day off to present a little Tour de France primer.
