Kilometre 0 - The coach
At La Rosière in the Alps, Geraint Thomas won the stage and took the yellow jersey and, more than an hour later, Mark Cavendish crossed the line last and well outside the time limit.
For Rod Ellingworth it was a bitter-sweet day because both riders were graduates of the British Cycling Academy he founded and ran.
The next day, on the road to Alpe d'Huez, Orla Chennaoui travelled with Ellingworth in a Team Sky car and asked him about his relationship with both riders and his approach to developing youngsters to cope with the demands of professional cycling.
