Decades ago I certified a course for Ashrita Furman, whose hobby was breaking Guinness world records. I can't find "Furman" as a measurer in the course list, so perhaps someone else did it on his behalf. It may have been connected with pogo-stick jumping, somersaulting, or something equally odd. Anyway, he set a record on the certified course.
He's still at it.
I applaud his stamina.
