At 22, the condition deteriorated, to where he needed 30 hours of dialysis, a week. This led to a very restricted life style with a salt free diet, low fluid intake, and breaks away limited to where there was dialysis availability, for next 6 years. After a successful kidney transplant, in 1978, Peter was soon competing in the domestic Transplant Games, and then representing Great Britain, in the World Transplant Games, 6 times, winning medals, including 2 golds. Peter's local running club, which he had joined, happened to organise the first mass marathon in the country. In 1981, he became the first transplantee to run a marathon, followed by two more marathons that year. He was involved with the Transplant Games for more than twenty years, being a member of the management committee, the Birmingham team manager, event organiser, and also as a competitor.
