Actress and model Kelly Brook said today she will join the Mayor of London on a mass participation bike ride round the capital.

Brook was helping Boris Johnson launch his Skyride, a large-scale cycling event taking place on Sunday, September 20.

Cyclists will enjoy traffic-free roads in the city centre and the 15 kilometre route will take riders past landmarks such as Buckingham Palace, Trafalgar Square and the Tower of London.

Brook said she was looking forward to joining the Mayor, alongside Olympic medallist Chris Hoy, for the ride.

"I'm going to be there, Boris is going to be there, Chris Hoy is going to be there, it's a really exciting event, it doesn't matter if you're not a professional.

"I'm not really feeling that athletic but I do ride my bike on a regular basis, I do love cycling.

"It's just a fun day out, it's for everyone of all ages and all standards of cycling."

Keen bike rider Mr Johnson said he had some tips for the more timid participants. "Have a go and remember you don't have to go too fast. I always cycle in a suit, I barely break into a sweat, I scarcely perspire I go so slowly," he said.

"The danger is not behind you, it's in front of you so be aware."

He added: "You would be absolutely crazy not to hop on your bike. Skyride is a fantastic opportunity to see parts of central London in a way you never normally can. You can use your bike without any fear of being interrupted by a car."
