Today sees the end of an exciting week of racing at the Tour de France - especially for fans of Mark Cavendish. Cav took three stage wins which makes him the second most successful Tour stage winner of all time, after the legendary Eddy Merckx. Many who had written Cav off as being 'finished' had to eat their words as he used skills learnt on the track to lunge ahead of André Greipel, beating him by millimetres! Ride Velo thought we'd take this opportunity to celebrate the sprint finish by revealing the science, tactics and psychology that goes into achieving the top podium position.
