‘Keep fit, while you can’ - 85-year-old grandfather is the only person to swim in every Midmar Mile

85-year-old Mike ‘Buthie’ Arbuthnot swam his 45th Midmar Mile, which is the world’s largest open water swimming event, on Saturday February 10 2018. CORRECTION: Mike Artbuthnot is the only person to swim in every Midmar Mile since its inception. Mike Pengelly has also swam 45 times but one year organizers allowed him to swim the race a week early, because the race clashed with World Lifesaving champs.
