Stage Seventeen

Gary Imlach and Chris Boardman present highlights of stage 17. A key day in the mountains on a day the Tour de France becomes 100 per cent Swiss. The peloton crosses the cantons of Berne, Vaud and Valais. They tackle two category three climbs, before embarking on a final, two-step ascent that starts with the Col de la Forclaz, a category one, 12.6km climb at an average gradient of 8.2 per cent. It finishes with the super-category Finhaut-Emosson - 10.4km at 8.4 per cent touching 12.3 per cent in the final kilometre. Commentary by Ned Boulting and David Millar with Daniel Friebe reporting from the roadside.
