Can't remember which year but it was when it was the Schleck brothers vs Contador. Contador was winning and Andy made an early break and rode like a beast trying to make up time. Had Merckx cheering/encouraging him from a lead vehicle. I think it was the same year Andy's chain dropped on a climb and Contador took advantage of it. Contador ended up winning, but after the doping violation, Andy was given the title years later.
