For 21 gruelling days 198 riders will travel 3,664km over some of Europe's most challenging terrain. The Tour de France isn't for the faint-hearted - and Dean Downing, a professional cyclist from Rotherham, as been founding out why.
He's never ridden the tour, but has been putting his body through a series of tests down at Leeds Metropolitan University.
