Masters swimmer John Griffin is on course to complete his challenge in 2024 of swimming a million metres, while aiming to raise £1 million in the process for the Cornish Air Ambulance. John is 70-years-of-age and has never swam this distance over a period of a year before, but wanted to set himself a lofty challenge in retirement. He lives in Cornwall and the Air Ambulance is close to his heart.
