Bradley Wiggins has won seven Olympic medals and a world time trial title, and he is Britain's first ever Tour de France winner.

But at 18:30 BST today, he will attempt to break the record for the furthest distance travelled in an hour. It will be painful, and could be gruesome at times.

His crack at the record of 52.937km, held by Alex Dowsett, could take in as many as 221 laps of the 250m track, with laps taking as little as 16.3 seconds to complete.

If everything goes perfectly, Wiggo will travel 55.25km. But the high air pressure around London today could make it difficult to achieve that lofty aim.

There are plenty of things you can do in an hour.

Wash the car? Make an apple strudel? Watch one episode of Jack Bauer (not the cycling one) kicking backside in 24?

Or, you could do more than 200 laps of a velodrome in an attempt to travel the furthest distance ever covered on a bike.

That's the option Sir Bradley Wiggins has gone for today, and we're with him all the way at the Lee Valley VeloPark, where the London 2012 track cycling was hosted.
