Start
Key events can be any memorable event, for example an impressive victory but also a major crash, bold solo or anything that makes for sporting memories.
Without any victory and only 21 racedays before the start of the Tour de France, there was doubt if Lance Armstrong was in shape for a 7th tour win. With 4 kilometre to the line in the opening time trial, Armstrong overtook his long time opponent Jan Ullrich and came in 2nd, three seconds behind David Zabriskie.
