North Runcton man Malcolm Souza-Lewis is taking part in the British Transplant Games in Bolton from next Thursday.
Mr Souza-Lewis has competed many times in the competition, the last being in Kent in 2012 when he came back with three gold and two silver medals.
That won him selection for the GB team to the World Transplant Games in South Africa but operations to remove his gall bladder and then replace his right knee knocked him out of competition for more than a year.
Mr Souza-Lewis said: “The staff at Lynnsport’s Bodyworks have been helping me to strengthen the requisite muscles for the throwing events and to get the replaced knee to be as good as possible.”
Mr Souza-Lewis is competing in the 60-69 years age group for the last time this year, in the javelin, discus, squash, high jump and cricket ball throw.
He has hopes of medals and would love to be selected at the age of 70 next year for the Transplant World Games in Argentina.
