A crowd of spectators is lining Passo Campolongo, 6,152 feet high in the Dolomites of northern Italy, and screaming "Die! Die! Die!" at me. It's a bit disconcerting, especially while I'm pedaling up steep switchbacks where it takes every ounce of strength and focus simply to move forward. In fact, the word is "dai," and what they're really urging me to do is: "Go! Go! Go!"
