Havik and Stroetinga maintain lead as Dideriksen takes it at Six Day Berlin

Dutchman Yoeri Havik and Wim Stroetinga maintained their lead but now have three teams just a lap behind in the standings, as Amalie Dideriksen moved into the lead of the women's omnium with another consistent day of riding in Germany.

The action began with a fast and furious 30-minute Madison chase as Britain's Andy Tennant and Chris Latham were continually frustrated at their inability to escape a field intent in not letting them climb the leaderboard.

In the end there were six teams to take a lap, with Morgan Kneisky and Benjamin Thomas winning the sprint to the line to take the win.

And Thomas continued their strong start to the day with a second place in the Longest Lap, behind Denmark's Marc Hester.

Another second place came their way in the 60-lap Derny B final, but it was Havik and Stroetinga that rode away from the field to increase their lead in the overall standings.

The closing 45-minute chase was a cagey affair, with no-one being able to escape the grasp of the peloton until the final 15 minutes.

And it took a mammoth effort from Austria's Graf and Muller to gain the all-important lap, with the latter in particular putting in a huge turn to bridge the gap and complete the lap.

The result left Havik and Stroetinga out in front 412 points, followed by Belgium's Kenny de Ketele and Moreno de Pauw who are one lap and ten points worse off.

Pim Ligthart and Jens Mouris also sit a lap back, but with only 324 points to their name, while Graf and Muller only have 260 and will have to rely on their Madison skills to pull off a shock victory on Day 6.

In the women's event Katie Archibald extended her lead in the standings by winning the night's opening 10km points race, with Canada's Stephanie Roorda in second and Dideriksen in third.

But the Six Day London champion slipped back in the standings after an early exit in the elimination race, allowing Dideriksen to take the win, and the overall lead in the standings.

Archibald did trim that lead in the final event, though, with a seventh place finish in the 10km scratch race – won by Canada's Laura Brown when she took a lap on the field – while Dideriksen could only manage tenth.

Heading into the final day, the Danish road world champion leads Olympic team pursuit champion Archibald by just two points, with Roorda and Germany's Anna Knauer a further nine back in joint third.

Elsewhere, in the sprinters' event, it was another day of domination by home favourite Maximilian Levy, who set the fastest 250m flying lap time before beating compatriot Robert Forstemann in the A sprint final.

The two Germans were the only ones to dip below in the flying lap, with Levy getting the better of his rival by 0.022s – setting a time of 12.830s.

In the B final there was victory for Joachim Eilers over Tomas Babek, while Philip Hindes beat Rene Enders and Nate Koch in the C final.

But the American went from last to first in the final sprinters' event, taking keirin victory and his first win of the week, before unleashing his trademark celebration – ripping his jersey open.

The night closed with a second Derny ‘Stayer' win of the week for Reinier Honig. Sportsbeat 2017
