Hello and welcome to the Cyclingnews live coverage of stage 5 of the BinckBank Tour.

As we join the action, the seven-rider break of the day remains out front.

They jumped away after 25km and currently have a lead of 4:20 with 80km to race.
This is a image of the seven attackers.
The peloton seems happy to let the seven hang out front for now. But the pace has increased a little and so the gap should begin to fall.

There's no sign of Docker's thick 'tache.
The riders started on wt roads and under grey skies but avoid so far avoided any heavy rain.

Boom won the Eneco Tour back in 2012 back in 2012 and so has a real chance of victory in this year's newly-named BinckBank Tour.
He will have to fight for time bonuses but is suited to the hilly stages at the weekend.
Boom was asked one question in English before going onto the podium. He didn't fully explain his gesture but talked about 'anger and happiness'
“The spring Classics were not what I hoped for this year and there was a lot of anger and happiness when I passed the finish with this victory,” he said.
“I’ve worked really hard in the last few weeks and months to get back in good shape, that’s why I’m so happy.”
Asked if he is back to his best, Boom said: “I hope so.”
As expected, the stage was like a mini-Amstel Gold Race, with the twisting, narrow roads and series of climbs making for a selective and fascinating race.
Speaking in Dutch after his stage victory, Boom said of his gesture at the finis
"Those people who know me will know why this was."
He also talked about his attack with 2km to go.
"I was lucky to still be up front. When Sunweb broke it up, I sat in the back because I was slowed by a fall. In that favourite group I just went along."
"At 2 kilometres from the end I went a little faster through a corner and I thought: this is my moment. The others expected Sagan to close the gap, which I could benefit from."
This screen grab shows Boom in the leader's green jersey.
