Bradley Wiggins and Mark Cavendish lead going into final day of racing in Ghent

A lap ahead of their main rivals overnight after a dominant display on day four, Wiggins and Cavendish saw Kenny de Ketele and Moreno de Pauw - the pair that beat them in last month's London Six Day - wipe out their advantage in the first madison and take the lead courtesy of their superior points total.

But five-time Olympic champion Wiggins and 30-time Tour de France stage winner Cavendish took a lap in the final event of the day, the second madison, to boost Wiggins' chances of ending his career on a high.

The 36-year-old has long hinted this could be his final competitive race, with the city of his birth providing an appropriate exit venue. However, last month Wiggins suggested he could be tempted to carry on for another season and on Monday told reporters to "ask him on Sunday" what his future held.

After finishing second in Saturday's points race, the British pair were runners-up in the team elimination before winning the one-lap time trial.

They were second to De Ketele and De Pauw in the first madison and the 500 metre time trial, but second-place finishes to Olympic champion Elia Viviani and Ilgo Keisse in the last two events were enough to restore their lead.

Both De Ketele and De Pauw in second and Viviani and Keisse in third are a lap down on Cavendish and Wiggins, but possess better points totals, meaning they would overtake the leaders if they make up the deficit.
