I was just looking through my Velo News Giro guide and the most interesting historical fact that I've read so far is that Coppi's five victories (1940, 47, 49, 52, and 53) have a 13 year span. It would take more Googling than I'm willing to do, but I wonder if there is a *** span for a GT or even a classic. Quick Wiki: it looks like Bartali had 12, and Gimomndi 11. Contador has 9.
