He's been shot at, subjected to blistering temperatures, had numerous punctures and yet still he keeps going. In January cyclist Jamie McDonald started his bike ride from Bangkok to Gloucester.
He's funded the entire trip himself to raise money for a children's charity at the Gloucestershire Royal Hospital.
His father says he is proud of his son's efforts but also a little concerned.
At one point he cycled into a war zone on the Afghanistan border. The hostel was staying in came under fire. His father, Donald, is rightly concerned about the dangers.

It was frightening, scary but you also have that apprehension that something will happen but hopefully he will be back here in one piece.
Jamie's cousin Kevin Brady is flying out to Turkey to meet up with him and they'll finish the final leg of the journey together. He's met up with young patients at the Gloucestershire Royal Hospital, which is to benefit from their fundraising. His costume is appropriate when you hear where they are due to rendezvous.

I am flying to a place in south west Turkey called Batman. It's only right, to raise a bit of awareness, I'll dress as Robin and take a Batman costume out to him.
The pair are raising money for the Pied Piper Appeal, which was set up to help sick children in Gloucestershire. You can find out more on Jamie's Facebook page.
