Dougie Lampkin MBE has become the first person to wheelie the entire length of the Isle of Man's 37-mile TT course.
The 40-year-old completed the course in one hour and 35 minutes, navigating more than 200 corners and climbing 422m (1,385ft) - all on one wheel.
Lampkin, a 12-time world champion trials rider, told the BBC: "From the word go it was so intense. The strain on your arms, legs feet, neck and everything else was just unreal.
"Up to ten times I came close to dropping the bike and I thought I'd lost it twice. When you've lost your balance and your right leg comes off, you're in massive trouble. I couldn't rely on the rear brake at that speed."
