Daniel Lloyd (Team IG-Sigma Sport) returns with his final preview video of the 2012 Tour de France. 

Lloyd takes to his time trial bike to preview stage 19, a 53.5km time trial from Bonneval to Chartres that will require one final effort from the GC contenders.

After three weeks of racing, the goal for many will simply be to finish the race, says Lloyd, but those at the sharp end, Bradley Wiggins especially, will be required to give of their best.

Tomorrow, the time trial’s soubriquet, the race of truth, will take on added significance. Will it be the stage on which Wiggins seals a first British victory in the Tour de France?

Check back later today for a full report, photo gallery, and video highlights.
