An inside view into cycling's most prestigious event and the people who have helped Lance Armstrong win an unprecedented six times

Lance Armstrong's place in the cycling history books is assured. Winner of the Tour de France a record-breaking six times, he is regarded as one of the greatest individual talents the sport has ever seen. Perhaps his most compelling victory was in 2003 when he won the coveted Centenary race. However, without the team of brilliant athletes assembled to support him - the domestiques - victory in the Tour would have been impossible.

Not only do these superbly trained athletes ride alongside the team leader, supplying water and equipment, but they also create a moving stream of energy that is vital for competitive success. In 2003, Lance Armstrong's domestique, Victor Hugo Peña, actually took over the yellow jersey and stepped into history. A Significant Other is the story of that race but also of these unsung heroes of the sport.
