With 500 meters left for the goal at the observatory in Arcos de las Salinas, Madrazo took the plunge and won the stage ahead of the stable mates Jetse Bol and Jose Herada, who for a while were loose with over ten minutes to the cluster.

- Winning here is one of the biggest things you can do as a cyclist. It was a dream come true, the Spaniard said of the win, his first in a Grand Tour, in front of the home crowd after 170 km.

Colombian took over the overall lead

There were changes in the summary after Miguel Angel "Superman" Lopez subtracted the total cyclists the final kilometers in the heavy finish and finished four on the stage. The Colombian now leads a total of 14 seconds ahead of Primoz Roglic and 23 ahead of Nairo Quintana.

"There will be more opportunities in the coming days," Lopez predicted.

This week's remaining stages up to Monday's rest day will offer tough backy and mountainous conditions and the top match will get a better contour.
