Michal Kwiatkowski timed a late attack to perfection to win stage five of Volta ao Algarve and seal the overall victory, with Geraint Thomas second on the podium.
Kwiatkowski emerged from a small elite group on the final climb to attack solo leader Zdenek Stybar with two kilometres to go and pass him to secure a dramatic win.
He was pursued by Ruben Guerreiro and Serge Pauwels, but they were unable to catch the Polish rider who won from Guerreiro by four seconds.
Thomas finished in a chase group that was 1’47” behind Kwiatkowski, finishing second overall with ‘Kwiato’ earning the points jersey and Team Sky finishing as best overall team.
Kwiatkowski revealed that the team had to readjust their tactics during the race, but with support from Golas he was able to secure the stage win from the lead group.
He said: “We had our eyes open at the start and we felt that was the best way to defend yellow and to defend second place and even go for the stage win.
“I’m very thankful for the team and especially to G for that opportunity. Nobody expected the race was going to go that way, it was not a typical way to defend a yellow jersey.
“Massive thanks to Michal Golas - he was amazing today, protecting me in the breakaway and he made this win possible."
