Chris Horner grabs lead as Vuelta heads for very exciting finish

This year's Tour of Spain is headed for a grandstand finish with everything to play for between the top four riders. In today's penultimate mountain stage Chris Horner overcame Vincenzo Nibali's three second lead, to take the leader's jersey by three seconds. At 1.06 min Alejandro Valverde is close behind and Joaquim (Purito) Rodriguez, today's stage winner, not out of contention at 1.57 min. Everything will be down to tomorrow's fearsome climb of Angliru.

Can Chris Horner take the Vuelta at nearly 42 years young? Can Nibali recover or is he shot – having lost time on the last three mountain stages? What of Valverde or Purito? Still possible for any one of these four to win! Not to be missed tomorrow.

Vuelta enters its final week with four in the frame

After yesterday's rest day the Vuelta resumes with some tough stages before the finish in Madrid on Sunday. Until Monday's stage it looked like Vincenzo Nibali would be the comfortable winner. However losing a little time on Monday means that he is now only 28 seconds ahead of nearly 42-year-old Chris Horner, 1.14 mins ahead of Alejandro Valverde and 2.29 ahead of Joaquin Rodriguez, who is often very strong in the third week of a major tour.

After a flattish stage today, there still are three mountain stages to come culminating in the very steep Angliru climb on Saturday, where the Tour of Spain could yet be decided.

Chris Horner, Nibali's closest rival, has ridden a remarkable race, especially for a man of nearly 42. This is certainly easily Horner's best ride ever in a major Tour and he has looked strong on all of the climbs. After Armstrong there are inevitably doubts, so I just hope he is clean.
