92yr old Ladislav Nicek has been competing in the annual Winter Swimming Championships in the Vlatva River for over half a century, and has until this point only missed a few events. Up to 70 ‘otuzilci’ (hardy fellows) brave the icy waters in an event which attracts a huge amount of media coverage, a large percentage due to the efforts of Mr. Nicek. He even organises the event every year before jumping in himself.
Nicek is one of five elderly athletes profiled at Vitabits. http://www.vitabits.co.uk/health-blog/health-freaks/ -Thanks, David!
