A brave biker, who miraculously survived a head-on collision with a lorry in India, is to defy the odds and run the London marathon later this month.

Roy Clark, 48, from Wandsworth, woke up in intensive care in a southern Indian hospital in February last year following the horrific crash not knowing if he would ride a motorbike or even walk again.

The collision left him a pelvis broken in five places, six broken ribs, a shattered vertebrae and fractures to his shoulder and hand.

But having returned to the UK and made a surprising yet full recovery Mr Clark is ready to join the 37,500 runners and pound the streets of London on April 21 to raise £100 per mile for children's charity The Rainbow Trust.

He said: "Having got to know Rainbow Trust in my role as guide on many fundraising adventure trips across India, I know just what a difference their work makes and the role they play in providing emotional and practical support to families who have a child with a life threatening or terminal illness.

"And so, when running the marathon became a very real option, I was determined to continue fundraising on their behalf."

"As a result of another accident just over five years ago, which nearly cost me my foot, I think it’s fair to say training is quite a challenge.

"However, knowing the uphill struggles the children supported by Rainbow Trust face on a daily basis, I’m determined to finish the course and raise all the money I can."

Accompanying Mr Clark along the 26.2 mile journey will be a 6in Rainbow Trust bear mascot that accompanied him across India.

He added: "This little chap has travelled across India with us throughout all my Rainbow Trust adventures and as he now lives with me I thought it would be a shame if he missed out on this one."
