17 Hours to the Top. Leonid Boguslavsky Ironman Championship documentary (English subtitles)

Leonid qualified for the World Championships back in 2015, just 1.5 years after his first triathlon training. But Leonid was able to be at the start line on Kona Island only in 2022, at 71 years old and with a prosthetic hip.
How was this path for him? And why was it important for him to reach the end no matter what? In the documentary "17 Hours to the Top" he himself, his family, coaches, doctors and athletes find answers to these questions.
