Pendleton, who won the sprint at the Olympics in Beijing last year, will wear the creation on the first Green Britain Day, organised by EDF Energy to inspire Britons to cut the UK's carbon footprint in time for the London 2012 Olympic and Paralympic Games.

EDF Energy is asking people around Britain to "do something green for the team" on July 10 and sign-up to Team Green Britain a website full of ways to cut carbon emissions

Pendleton is supporting the initiative along with a number of her Olympic team mates including rowing champion James Cracknell, swimmer Eleanor Simmonds, Britain's youngest Paralympic gold medallist, rower Tom James and gymnast Louis Smith.

The day will culminate in a concert at The Eden Project in Cornwall starring musicians Paul Weller and the band Florence and the Machine.
 

Vincent de Rivaz, the chief executive of EDF Energy, which is sponsoring the London Games as sustainability partner, said: "Climate change is one of the biggest challenges facing us.

 

"As an energy company, EDF Energy has a responsibility to be at the heart of the solution to climate change and we have the expertise to help people use their energy more efficiently."
 

Sebastian Coe, the chairman of London 2012, said: "London 2012 is all about using the power of the games to inspire change and it's fantastic to see EDF Energy, the first sustainability partner of London 2012, taking this on in their activation.

"The Green Britain Day campaign is a great way for people to come together and make a difference."
