Do. Not. Miss. Stage 20. Mont Ventoux hasn’t been featured since 2002, and the Tour’s most feared climb has never loomed this close to the finish. Although they face no other climbs on the stage, riders will tackle the Ventoux from the south—its most difficult approach. The long, sustained 9 percent pitches (plus several shorter ramps past 10) are plenty tough; Ventoux’s rocky, treeless landscape adds to the eerie feel. Some riders say it’s like racing on the moon: There’s no air.

Betting Line: All bets are off; anything can happen here. In 2002, the day’s top 10 riders spread over four minutes between them and Armstrong almost doubled his lead on Joseba Beloki. There are no tomorrows, no next chances. Anyone who wants to win the Tour must go here, and now.

*Highest wind speed ever recorded at the summit: 199 mph
