A team of four cancer survivors are taking on what is said to be the world's toughest bike race.
the amount the team are hoping to raise
The money will go towards buying bikes for children recovering from cancer - encouraging them to be active is at the heart of what the team have set out to achieve.
I know how difficult it is to cope with cancer and I think if we can help in any way to help children with or beyond cancer, what better gift could we give? That exercise for them is so important.
Cyclists Fighting Cancer was set up by teammate Mike, as part of his own road to recovery. He was diagnosed with blood cancer nearly two decades ago. Since then, the charity has grown to provide hundreds of bikes to children across the country.
My life changed that day. It was a horrendous moment, I went from being some kind of superman to a hospital number and that was going to be my life for the next six years as it turned out.
For all four riders, crossing 3000 miles from California to Maryland in just seven days will be a challenge.
The route crosses twelve states and three mountain ranges - and attracts international professional riders.
They hope their adventure proves it is possible to lead an active life after cancer.
