Amanda Holden is set to cycle more than 250 miles in aid of a charity.

The Heart Breakfast presenter will pedal from Bude in Cornwall to London for Global's Make Some Noise.

The event, dubbed 'Amanda Holden's Big Ride To Work', will see the TV personality tackle the distance over a five-day period.

Ms Holden, who started on October 7, and will cycle through Somerset, Berkshire, Wiltshire, and Surrey before reaching the Heart studios in London's Leicester Square on October 11.

She will spend eight hours a day on her bike, and will finish on Global's Make Some Noise Day.

In the past, Ms Holden has completed the Three Peaks Challenge, a 10,000 feet skydive, and climbed to the top of Blackpool Tower, all in aid of Global's Make Some Noise.

Ms Holden said: "I can’t quite believe that I’m going to be cycling over 250 miles from my mum's house in Cornwall to London for Global's Make Some Noise - it’s a massive challenge.

"I’m told it’s not going to be particularly flat so I’m gonna have buns of steel by the end of this.

"Knowing that every mile I cover will help raise funds for those local projects providing a lifeline directly to those who need it most is what will keep me going.

"I can’t wait to see how much we can raise for Global’s Make Some Noise.

"I know we’ll get incredible support from our amazing listeners."

Jason King (JK), who is standing in for Jamie Theakston, will be in the Heart studio all week, cheering on Ms Holden and checking in on her progress.

He will also be speaking with some of the charities that Global's Make Some Noise has supported over the years.

He said: "Amanda is taking on a massive challenge this year, all to raise money for the fantastic projects supported by Global’s Make Some Noise.

"I’ll be right here in the studio, cheering her on every step of the way."

Suzanne Ryder-Richardson, director at Global Goodness, said: "We’re incredibly grateful to Amanda who once again is taking on a massive challenge to raise money for Global’s Make Some Noise.

"Every single donation to Amanda’s challenge can help to provide a lifeline to those who need it most, in the heart of communities, perhaps even on your doorstep."

Donations can be made on the charity's website as well as the radio website to support Ms Holden.
