He’s already a living legend and national treasure for his many achievements on the track, but now Graeme Obree is going after the human-powered land speed record on a home-built bike dubbed the Beastie. In this report from Channel 4 news he talks about his demons and motivations.

Graeme Obree twice broke the World Hour Record, amending his bike design as the UCI banned it to try and prevent an unknown upstart from Scotland challenging cycling’s greats.

He walked away from a professional road contract because the team expected him to participate in a doping programe.

In retirement, without the self-medication of racing targets and huge amounts of training, he succumbed to severe depression and attempted to take his own life.

In 2011, Obree came out, explaining that suppressing his gay identity had been a major cause of his depression.

In this interview, Obree talks about what he will personally get out of breaking the 83mph speed record, and how it felt to attempt the Hour Record over 20 years ago. As ever, he’s fascinating.
