World championship leader Jenson Button is to take part in a race at slightly slower than F1 speeds during the summer break, after agreeing to compete in the London Triathlon.
The Brawn GP driver is to take part to help raise money for the Make a Wish Foundation – and has got his two race engineers to also agree to join him.
The event on August 1, in which 11,000 competitors will take part, features a 1500 meter swim, a 40 kilometer bike ride and a 10km run.
"As you probably know I've been taking part in triathlons over the past couple of years as a way of keeping fit for my racing," said Button. "As we are so busy this year, I won't be able to do as many triathlons as I would like but thought that I would give the London Triathlon a go.
"It's the biggest triathlon in the world so I thought it would be a fantastic opportunity to raise money for a charity that is very close to my heart.
"I'm a Patron of the Make A Wish Foundation and have had the pleasure of meeting lots of kids who are supported by the charity at our tests and races.
"Make A Wish grants magical wishes to children and young people fighting life-threatening illnesses and it is a real privilege to be involved with them. The kids are so inspirational and hopefully we can raise enough money to fulfil as many of their dreams as possible."
He added: "Somehow I have even persuaded my two race engineers Shov and Bono to take part! They will be competing in the half distance event.
"So please dig into your pockets and sponsor me. Your money will be going to a very worthy cause and helping to make dreams come true for some very poorly children."
