Dan Martin: This year's Tour is all about who has the worst bad day

The mountains have arrived for the Tour de France peloton as the race begins its jaunt through all five of the mountain regions of France. La Planche des Belles Filles gets the honour of the first summit finish of this year's race.

Born in Ireland to a cycling family and later moved to the Isle of Man, so there was no surprise when I got into the sport. Studied sports journalism at university before going on to do a Masters in sports broadcast. After university I spent three months interning at Eurosport, where I covered the Tour de France. In 2012 I started at Procycling Magazine, before becoming the deputy editor of Procycling Week. I then joined Cyclingnews, in December 2013.
