Brailsford's marginal gains 'a load of rubbish', claims Wiggins

Updated: 

Bradley Wiggins has described British Cycling's marginal gains theory as "a load of rubbish".

Wiggins won five Olympic gold medals for Team GB - four on the track and one on the road - but it appears the 36-year-old was not a believer in some of the practices being preached.

With former Olympic champion Chris Boardman originally leading the way, British Cycling has attempted to gain an advantage over its competitors by developing advances in bike technology and other equipment.

British Cycling and Team Sky, for whom Wiggins worked alongside principal Dave Brailsford, have recently come under investigation regarding their medical practices during the 2011 Criterium du Dauphine.

Asked about the marginal gains mantra, Wiggins was scathing in his assessment, while also criticising Sky's former head of medicine Dr Steve Peters, author of 'The Chimp Paradox' - a book about coping with pressure that Wiggins' Team GB colleague and two-time Olympic gold medallist Vicky Pendleton swore was a major part of her success.

"A lot of people made a lot of money out of it [marginal gains] and David Brailsford used it constantly as his calling card," Wiggins said.

"But I always thought it was a load of rubbish.

"It's a bit like the whole chimp thing. At the end of the day, chimp theories and marginal gains and all these buzzwords - a lot of the time, I just think you have got to get the fundamentals right: go ride your bike, put the work in, and you're either good or you're not good.

"Sometimes in life or in sport, whatever, you're either good at something or you're not.

"That's what makes you a better athlete: your physical ability and whether you've trained enough - not whether you've slept on a certain pillow or mattress."
