I remember the first Tour that I watched that totally sucked me into the sport.
It was 2001 and it was specifically the climb of Alpe D'Huez. At one point, Lance Armstrong turns to make eye contact with Jan Ullrich and then works to drop him in the craziest attack ever. If you haven't seen it, you have to watch this video. Some of it is just training and shots from the race, but at 1:40 they show the look for the first time and then again at 2:19. Chills.
It doesn't hurt that cycling has tons of eye candy, in my opinion. One of my favorite pieces of eye candy is George Hincapie. Let's take a moment, shall we?
The view is nice. N'est pas?
My tour fanaticism isn't helped by the fact that I married a cycling enthusiast. At one time, my sweet husband had 4-5 different frames: 2 road bikes, a mountain bike, and a cyclocross.
Talk about eye candy! Here is my own personal hottie in one of his cyclocross races. (René is wearing an orange jersey.)
