As revealed in today?s Cycling Weekly the world time trial champion, Fabian Cancellara, is planning to ride the individual pursuit at the Beijing Olympics next summer.

The time trial specialist blitzed the rest of the field at the Tour de France prologue in London and now the Swiss track coach Markus Nagel wants him to turn his hand to the pursuit.

Nagel admits it?s not as easy as getting up one day and transforming road speed into track craft, so Cancellara will be testing at the velodrome in Aigle, Switzerland, before Christmas.

And, if the times are good enough, the CSC rider will enter the final round of the World Cup track competition in Copenhagen in February in a bid to qualify for the Olympics.

So, if Wiggins and Cancellara do go head-to-head in Beijing, who?s the favourite?

SUMMARY
Cancellara is clearly one of the most accomplished rouleurs in the modern peloton. His power, technique and pure speed was evident to the huge London crowd as he demolished the field at the Tour prologue in July.

Cancellara covered the 7.9-kilometre course in a time of eight minutes and 50 seconds – an average speed of 53.7 kilometres per hour. Wiggins was 23 seconds slower.

Wiggins? personal best for the 4,000 metres pursuit is four minutes and 15.165 seconds, set in Athens ? an average speed of 56.47 kilometres per hour.

Cancellara?s status as the best time trial and prologue rider in the world right now may not be threatened in the near future but the track is a whole different basket of onions.

When it comes to a fixed gear, a wooden track and unimaginable pressure, Paris-Roubaix, Tour de France stages and world time trial titles will mean absolutely nothing ? and that?s assuming he even manages to convert his proven road ability to the track in his testing sessions.

VERDICT
Wiggins remains the clear favourite, particularly given Cancellara?s lack of time to learn what the track?s all about.
