There are just two stages left in the 2012 Tour de France. Bradley Wiggins has held upwards of a two minute lead for a week now, and all signs point to him capturing the championship in Paris. That being said, there's still plenty of racing left to do and a lot could change.
The 19th stage of the Tour will commence on Saturday. It'll be a time trial of just 53.5 kilometers, taking the cyclists from Bonneval to Chartres. The ride is pretty flat for most of the way, although there are some hills in the early parts that can provide a challenge.
As for TV coverage, you can find Stage 19 televised lived on NBC Sports Network beginning at 5 a.m. PST. That's 8 a.m. on the east coast.
