Ahhh, du Galibier. Switchback after switchback of asphalt hell. Hell if you're on a bike, but heaven if you're watching the world's best cyclists do the work. For 18 kilometers, a ribbon of pain and lactic acid wobbles and weaves its way up the grotesque, treeless slopes of the great French kingmaker.

Yesterday in Stage 9, between Val-d'lsere and Briancon, the boys on the bikes rolled themselves up not only les col du Galibier and du telegraphe, but also the Beyond Category (HC)-rated Col de l'Iseran climb. Three rated climbs, 159.5 kilometers, more than 4 hours. Lots and lots of opportunities for General Classification (GC) contenders to attack and try to put time into their rivals.

Judgement day.
