Leader Martin and 2014 winner Nibali crash (Reuters)

By Julien Pretot LE HAVRE, France (Reuters) – There’s never a dull moment on the Tour de France and Thursday’s Stage Six was no exception as leader Tony Martin broke his collarbone in a crash, sending 2014 winner Vincenzo Nibali and others tumbling. After a few days of crashes and nervous racing the peloton took it relatively easy on the Normandy coastline until the last kilometre when Garman Martin lost his balance and, almost like dominos, several leading contenders followed suit. “Confirmed broken collarbone for Tony Martin,” his Etixx-Quick Step team said, without giving any clues as to whether he would race in Friday’s seventh stage.
