Hmm...I don't know. Soler looked like he was going close to full gas at the same time the gap dropped by ~30 seconds and Valverde went back into virtual 2nd.

Edit: And as I type this Movistar riders are still taking full turns in the chase. Pulling through hard.

Edit Edit: I think it is plausible that Soler was trying to soften up the peloton so Valverde could try to force a split. Which did briefly work.
