Travis Pastrana has made a name for himself as the extreme sports superstar willing to go that bit further than most of his peers.
Whether it was becoming the first person to complete a double backflip on a full-size motocross bike or backflipping into the actual Grand Canyon, the 33-year-old has achieved a lot over his storied career.
His latest stunt came on the River Thames in front of the O2 as he completed a flip between two barges.
Pastrana had just 45.7 metres in which to reach take-off speed and just 11 to come to a stop before the barge he landed on turned into the Thames.
In flipping over the 23-metre gap, Pastrana became the first person in 11 years to try the trick.
The last person, Mike Metzger, fractured a vertebrae when attempting the same thing between two barges in Los Angeles.
The multiple-time X Games champion was in London to promote Nitro Circus, his collective of extreme sports personalities, who are touring in Europe this winter.
