As we join the action from the Cyclingnews blimp, we now have 14 riders in the break of the day, with the Katusha team leading the chase for leader and local hero of the day Joaqium Rodriguez.
The break is a serious threat to Purito, who wants to win on the steep climb to the finish.
None of the riders in the break are a threat to the overall lead of Esteban Chaves and so the Orica-GreenEdge team is not doing a lot of the chasing.
Sadly another big crash in the peloton left several riders hurt but none of them seriously injured.
Alejandro Valverde (Movistar), Tom Dumoulin (Giant - Alpecin), Fabio Aru, Mikel Landa (Astana), Samuel Sánchez (BMC), Domenico Pozzovivo (AG2R - La Mondiale) and John Degenkolb (Giant - Alpecin) are among the riders involved in the crash.
They all got going again but Valverde went to the doctor's car for some treatment.
123km remaining from 168km
The stage is largely flat until the first asssault of the Alto de Puig Llorença after 126km. The riders then drop down to he coast and then climb Alto de Puig Llorença agin, with an extra 500m of climbing up to the finish.
The Alto de Puig Llorença is only 3.3km long climbs at at 8.9% with some steep sections at 15% or even more. If should offer another thrilling finale.

The break has extended its lead to 5:20 after the feed zone. This will be a pursuit match all the way to the finish.
Purito Rodriguez is keen to win the mountain finish after his father spent time painting his name on the road during the night.

The @mtjallingii break has 5'14" after 76km. #LaVuelta2015
The average speed for the race is 41.3 km/h after two hours of racing.
The whole Katusha team is lined out on the front of the peloton. They know it is important to reduce the gap before the first climb of the Alto de Puig Llorença after 126km.
The gap to the break has fallen but only to 4:00.
However the break is working pretty well as they follow the coast road.
65km remaining from 168km
The peloton is rolling at 50km/h.
Following the abandon of Peter Sagan, Alejandro Valverde (Movistar) is wearing the green points jersey.
Watch out for him on the steep stage finish.
The race is 15 kilometers from the Alto de Puig Llorença. The race is about to be shaken up.
The riders are passing through Calpe, where so many of the riders come to train in the winter. As a result many know the roads and the climbs of today's stage.
55km remaining from 168km
The gap remains steady at 4:00
Katusha is still leading the peloton but the other teams are positioning themselves for the climb.
The Katusha riders have been leading the chase for more than two hours. Rodriguez really wants this one.

There are huge crowds at the summit of the climb.
Omar Fraile (Caja Rural-Seguros) saved his effort for the final metres and managed to edge past Cattaneo to take the maximum points.
There is a headwind on the climb and so the big names are ready steady this time up the climb. It will be very different for the last time up the climb.
The peloton goes over the top but on the final climb they turn sharp left and climb for another 500 metres.
The descent is wide but includes several nasty corners.

Looks like Aru is confident for today, Sanchez has joined the chase at the front of the bunch.
Nobody has helped Katusha do the chase today but now they've realised that they will have to do some work if they want a chance to win the stage. Movistar and Astana are helping the chase.
Orica is also on the front, riding to protect Chaves' lead and perhaps target the stage victory.
Maxime Bouet (Etixx - Quick-Step) kicks again at the head of the break, with Pavel Brutt and Thomas also going with him.

Today's stage was expected to produce some fireworks but nobody thought the gaps would be so big and the GC would be shaken up so much.
It was Dumoulin's seventh career win but has confirmed he is an overall contender at this year's Vuelta despite, or perhaps because, he crashed out of the Tour de France.
Dumoulin was stunned to have won. “Unbelievable,” he said after fighting to catch his breath.
“I could have never imagined this. Yesterday, I had a really bad day. The team told me, just to keep going, and see how it goes, and today it ended pretty well.”
Chris Froome was disappointed not to win today.
"I thought I had it there for a second but Dumoulin is showing incredible form in this race and hats off to him. He's a young rider with a bright future ahead of him."
Froome added: "The guys did a fantastic job for me today, keeping myself, Nico Roche, Nieve and Sergio Henao -the four climbers, at the front of the race."
"I don't think my attack was too far out. I gave it everything. I did try and ride more conservatively at the bottom to save something for an effort at the top if I had the legs. i'm just happy I was up there and didn't lose too much time today."
Rafal Majka took fifth place atop Cumbre del Sol and moved into ninth in the GC.
"Today I didn’t feel so good and I tried to attack in the finale to gain some meters before the finish. But when the climb is this steep, every hundred meters feels very long but still it’s not bad at the end and I finished fifth and move into the top ten in the general classification", he said.
"We wait for Andorra and the last week, we still have many mountains with longer climbs, which are more different. I’m satisfied with this first week and my teammates have worked for me perfectly."
"But we have to wait, we also have the long time trial and we have some big favourites here but I’m still there and today I tried."
"I had an advantage with 700 meters to go but I didn’t believe that I would take the win. I told my teammates that I was suffering a bit today and they worked to position me at the front before the final climb. Everybody has bad days and I think I had mine today. It wasn’t the same legs as two-three days ago but we have many days to go".
