Isle of Man wheelie challenge: Dougie Lampkin does TT lap on one wheel
A motorcyclist has become the first man to officially wheelie around the Isle of Man's 37-mile (60.725 km) TT course.
Dougie Lampkin, a 12-time world champion trials rider from Skipton, North Yorkshire, battled high winds as he navigated more than 200 corners and climbed 1,385 ft (422m) on one wheel.
"It feels fantastic," an emotional Lampkin, 40, said afterwards.
His lap around the Mountain Course - in which riders usually reach 200mph - was clocked at one hour and 35 minutes.
Lampkin, who lived on the island for nine years, said: "The last 15 seconds were really lovely - the rest of it was a challenge!"
He completed his historic lap on a highly modified Vertigo Combat Ice Hell 300cc - a fuel-injected single cylinder two-stroke machine.
His attempt, originally scheduled for Saturday, was delayed for 24 hours because of 55mph winds.
As expected, the infamous mountain section made for tense viewing as Lampkin fought gusts of 40mph during Sunday's lap.
"It wasn't over until a couple of metres from the end but that last couple of metres was just amazing," he said.
"From the word go it was so intense. The strain on your arms, legs feet, neck and everything else was just unreal."
Lampkin added: "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."
Multiple world endurance champion David Knight tweeted: "Massive well done to Dougie for doing the TT course on one wheel, some achievement that and looked proper tough 👍👍👍 #Redbull
Other to tweet their congratulations included former Formula 1 racing driver Mark Webber, television presenter Suzie Perry and cycling star Ed Clancy.
Lampkin, who has won five consecutive World Indoor and seven consecutive World Outdoor Championships, spent seven months training for his latest challenge.
