Stage 20 of the 2012 Tour de France is the traditional run to Paris, a 120km stretch from Rambouillet to the finishing sprint on Champs-Élysées. The General Classification for the race is extremely unlikely to change. Bradley Wiggins (Sky) is in yellow and will remain there at the end of the day, even if his rivals broke tradition and attacked Team Sky would be able to chase them down without too much trouble.
That leaves the stage for the sprinters, and the final sprint of the most prestigious race in cycling is a prize they've been dreaming of the entire race. Mark Cavendish (Sky) holds the record for Tour-ending sprints, having won the last three years running. He'll have some serious competition in the form of Peter Sagan (Liquigas-Cannondale). Sagan has a lock on the Green Jersey and would undoubtedly like to put an exclamation mark on his first tour by winning the final sprint.
Television coverage of the stage begins at 5 a.m. PT on the NBC Sports Network, with a Tour recap on NBC at 10 a.m. Fans can watch online via Tour de France Live, subscription required.
