Current holder: Bradley Wiggins (54.526km)

The Hour record is one of the most prestigious records in cycling with roots dating back to 1893 when it was set by Henri Desgrange, the man who would go on to create and run the Tour de France. In the mid 1990s the record was repeatedly broken on increasingly advanced equipment forcing the sports governing body, the UCI, in to creating a set of regulations that stifled record attempts and confused the record books.

The record was effectively reset this May when the UCI standardised the equipment regulations, bringing them inline with Olympic track cycling, and announcing the current record of 49.7km (previously called the ‘athletes hour’ as it was set on equipment similar to that used by Eddy Merckx in 1972) would stand as the mark to beat.

Fabian Cancellara had expressed interest in attacking the record, but his challenge thus far has not materialised. Instead, his retiring team mate Jens Voigt successfully set a new record of 51.115km in Switzerland on September 18 2014, followed six weeks later by Matthias Brändle’s mark of 51.850km set on October 30. After Jack Bobridge’s unsuccessful attempt at the end of January 2015, his Australian compatriot Rohan Dennis successfully set a new mark of 52.491km on February 8.

Britain’s Alex Dowsett was the next to take up the mantle, and after having to postpone an initial attempt in February 2015, Dowsett successfully broke Dennis’s record by over 400 metres, setting a distance of 52.937 at the Manchester velodrome on May 2.

World and Olympic time trial champion Sir Bradley Wiggins then increased the record to 54.526km in London on June 7.
