Shake rattle and roll! The GC was all shook up on this sunny, testing stage, the first in the mountains. Greg Van Avermaet, last man standing from a nine-man break, won from a daring solo attack a good five minutes ahead of the much reduced peloton. Slowly but surely, the GC has started to take shape, as a Romain Bardet-initiated attack in the final kilometres served to further distance Alberto Contador while Vincenzo Nibali had been shelled with Peter Sagan by Movistar earlier in the stage on the Pas de Peyrol. This, however, was merely the first salvo.
