More than 200 UK transplant athletes, who have all survived either a heart, lung, kidney, pancreas, liver, small bowel or bone marrow transplant, will compete in the games.

Team Great Britain and NI will join more than 1,000 other transplant athletes from 70 countries across the globe.

Simon Randerson (pictured right with the Olympic torch at the London Aquatic Centre) from Greenwich in London had a liver transplant at King’s College Hospital 14 years ago.

Simon, who has competed in five World Games said: “I am so delighted to have been selected again to represent my country at these amazing games.

“Each time I compete it is to honour my donor and his family. Without their gift of life, I would not be here. Organ donation is anonymous, and this is my way of thanking all donors publicly. It is amazing to think that after fourteen years with a donated liver I am fit and well enough to be taking on the world in the swimming competition.”

The World Transplant Games take place every two years and are supported by the International Olympic Committee. They represent the largest organ donor awareness event in the world, featuring a week of 17 sporting events.

Team manager Lynne Holt, said: “Not only are these athletes ambassadors for our country, but they are also representing the charity, Transplant Sport UK, and hope to raise more awareness here in the UK and globally, of the need for more people to sign on to the organ donor register.”

Simon said: “Selection onto the team is just the beginning. It is an enormous commitment of both time and money. For the next eight months I will be busy, keeping fit, training regularly in the swimming pool, attending team training meetings at Warwick University, promoting the games and the organ donor register and fundraising.

“Each athlete, although representing their country, must raise all the funding themselves. Unlike Paralympians, we get no government funding.

“However, this is an amazing opportunity to represent my country, celebrate life and in doing so, pay tribute to my donor. While I will be going for gold, promoting organ donation is the real goal.”
