As a young boy, doctors feared Jeremy Scott would not survive life-saving surgery to repair a hole in his heart.
Yesterday, the Aucklander completed a 50,000km global bike journey.
More than two years after he pedalled away from his London flat, the 38-year-old rode into the Auckland Medical School to shake the hand of the son of the surgeon who performed the life-saving operation.
Sir Brian Barratt-Boyes completed the surgery on Mr Scott in 1977 to repair a hole in his aortic valve.
"I have lived a very active life and played a lot of sport. Looking back, it is pretty cool to think as a child I couldn't run around a field and now I have been around the world," said Mr Scott, an architectural draftsman.
