An ironman triathlon is seen as the hardest one-day endurance event in the world. Consisting of a 3.8km swim, a 180km bike ride, followed by a full marathon, it is a huge undertaking for anyone, never mind a rookie with chronic kidney disease. Transplant Triathlete is Diccon Driver's story: an amateur triathlete who refused to let kidney failure stop him from racing.

Even after doctors told him his dream of finishing an ironman was impossible, he didn't give up. With just 20 per cent kidney function, he proved them wrong to complete his first ironman. Eight weeks later the disease causes his kidneys to fail completely and he starts dialysis to stay alive.

Now in need of a transplant, his brother steps forward as a live donor to give Diccon his life back. But will the operation be a success? And most importantly to Diccon, will he ever be fit enough to race again?
