Britain's Bradley Wiggins has smashed the UCI (International Cycling Union) hour record at the Lee Valley VeloPark in London.
Wiggins's distance of 54.526 kilometres today eclipsed the previous record of 52.937km, set by fellow British rider Alex Dowsett in Manchester last month.
However, Wiggins's ambitious target of 55km - which he had indicated beforehand might set a record that would stand for a generation - proved even beyond the British cycling great, who was roared on by a packed crowd at what was the 2012 London Olympic Velodrome.
Remarkably, world time-trial champion Wiggins still had the strength to lift his bike above his head after completing a punishing hour in the saddle.
Since the UCI, cycling's world governing body, unified the regulations surrounding the event last year, four riders have held the record: Germany's Jens Voigt, Matthias Brandle of Switzerland, Australian Rohan Dennis and Dowsett.
