Slate has a few interesting articles on the Tour, including ways to Lance-proof the Tour:

Make the mountains count: There are seven mountain stages this year, but only three of them finish on climbs, where the contenders generally ditch the pretenders. (Pay special attention to Stage 10 on July 12 and Stage 14 on July 16.) Compared to those used in other European cycling races, French mountain roads aren't all that steep. The ballyhooed Alpe d'Huez, which is absent from this year's race, averages less than an 8 percent grade. It's a handicap-access ramp compared to Spain's dreaded Angliru, which kicks up to 23 percent, and Italy's Colle delle Finestre, whose last five miles are unpaved. The solution: quantity over quality. Put mountain stages in the first week. And there are undoubtedly still a few dirt mountain roads in France—the organizers should have the daring to use one.
