Tour de France Highlights S2016E20 - Stage Eighteen

Gary Imlach and Chris Boardman present highlights of stage 18. Today's gruelling mountain time trial is only 17km long, but it is one of the most anticipated and feared stages of the race. The riders climb for 11km on gradients that, early on, reach double-figures. Start too fast, and running out of steam becomes a real and present danger. So success and failure in this year's Tour de France depends on finding the perfect pace today. The contenders will have no time to enjoy the stunning mountain setting - that delight is reserved for those watching on television. Commentary by Ned Boulting and David Millar with Daniel Friebe reporting from the roadside.
