Come on guys! Take a stand. I excluded the TdF option because it is a gimme. A no-brainer. But TdF excluded, do you want the Giro or the Vuelta? Or perhaps Paris-Roubaix?
Personally, I'm going with Paris-Roubaix, but at 5'10" and 138 pounds, I don't think that it is really quite suited for me. (Not that any of them are, of course!)
That is a great picture of Paris-Roubaix, by the way. I love a rainy April in northern France!
