There is no stopping Edvald Boason Hagen and his Team Columbia-HTC team mates at the Tour of Britain.
Despite a brave attack by Ben Swift (Katusha), Ian Stannard (ISD-Neri), Geraint Thomas (Barlworld), Serge Pauwels (Cervelo) and Thomas De Gendt (Vlaanderen), Columbia controlled the race all day and then mercilessly caught them 1.5km from the finish.
Boasson Hagen got another great lead out as the bunch crossed over the River Torridge and then accelerated away with three metres to go. Martin Reimer (Cervelo) tried to match him but could only just hold his wheel and hang on for second.
Russell Downing (CandiTV-Marshalls Pasta) again proved he deserved his place in Team Sky and a place in the Great Britain team for the world championships by taking third place.
Thanks to time bonuses, Boasson Hagen extended his overall lead on Kai Reus (Rabobank) to 19 seconds. It is not a lot, but with Columbia so powerful and so in control, it is difficult to who can stop him winning in London on Saturday. Downing is now fifth at 35 seconds.
"It's never boring to win stages," Boasson Hagen said, after his fourth consecutive win and seventh at the race in two years.
"The team was working really, really hard. That was a strong group in front and hard to close, we had to begin chasing early because they worked very hard."
"I was quite confident the whole stage except the last 10km, then it was a little different. But we got some help from some other guys, there was one Joker and Cervelo also did some small turns. It was good we got some help."
"The team started getting tired but then Tommy (Lovkvist) did an amazing last 2k to 1k. In last corner a Cervelo rider came through, I had a nice lead out from him, then I just went full gas."
The strength of Team Columbia is crushing for the rest of the field at the Tour of Britain. Boasson Hagen wants to keep on winning but is worried about pushing his team mates too hard.
"We have four stage wins, I'm really satisfied by that but I want to try for number five tomorrow. However the team working so hard today and the world championship is coming, so I don't want to kill them before that."
Team Columbia's final effort will be during Friday's 159km seventh stage from Hatherleigh to Yeovil. If they keep the yellow jersey after that, the criterium stage in London on Sunday will be a celebration stage.
