Action from stage 20, from Corvera de Asturias to Alto de l'Angliru. The stage is only 119 km long but there are two category 1 ascents before the riders reach what is often considered the toughest climb in Spain - the Angiliru with numerous ramps of over 20 per cent gradient. Presented by Gary Imlach, with commentary by Ned Boulting and David Millar, and reporter Daniel Friebe.
