Mark Cavendish's dreams of wearing yellow in the 100th running of the Tour de France ended amid the sort of chaos he feared as several of the favourites were felled by a major crash near the finish of stage one.

Marcel Kittel of Team Argos-Shimano took the stage win in Bastia after the three main favourites on the day - Cavendish, Peter Sagan and Andre Greipel - were caught in a crash around six kilometres from the finish.

That came amid confusion over where the stage would actually end after the Orica GreenEdge team bus became lodged under the banner at the finish line, causing organisers to temporarily move the finish line back 3km before restoring the route once the obstacle was removed with the riders bearing down.

Due to the confusion in the final kilometres all riders were awarded the same time for the stage and Ireland's Nicolas Roche was given 14th with Dan Martin 93rd.

But it is the German Kittel who will start tomorrow decked out in yellow after picking his way through the carnage and beating Katusha's Alexander Kristoffof to the line.

Cavendish had voiced fears about the impact of crashes during his pre-Tour media conference on Thursday, although even he could not have foreseen the chaotic finish to today's stage.

Johnny Hoogerland tumbled 15km from the line but that only hinted at what was to come.

Moments later, a bigger incident took down 2012 Giro d'Italia winner Ryder Hesjedal and Team Sky's Ian Stannard among others.

By this point, and with the peloton rapidly approaching town, organisers were frantically trying to remove the Orica GreenEdge team bus from the finish line after it had become wedged under the banner after apparently taking a wrong turn.

The teams were initially told the finish would be moved three kilometres forward, but once the bus was freed that just as quickly changed and the route was restored.

Barely had that news come through and the whole complexion of the race changed again as Sagan was caught amid a major tumble around six kilometres from the line.

Greipel appeared to suffer a puncture during the incident while Cavendish, though not hurt, saw his chances ended as he was caught in the queue.

The lucky few who were clear of the crash raced on to contest the sprint finish, although Matt Goss also fell 300m short of the line.

Also caught in the chaos was Alberto Contador, considered Chris Froome's main rival to win the Tour, who crossed the line with a ripped jersey though his Saxo-Tinkoff team quickly played down reports of an injury.
