An adventurer set to become the first person to run, swim and cycle the length of Britain has abandoned his challenge on the last leg after he twisted his ankle -- taking a selfie.
Eccentric Sean Conway, 33, had already CYCLED and SWUM the length of the UK when he left John O'Groats on his run earlier this month.
But the ultimate triathlete - who has survived jellyfish attacks and car smashes - tripped over a rock as he filmed a video selfie a few days into the last leg of his 2,800-mile quest.
He tried to continue but the injury put pressure on his knee and after limping on for a couple of days he was forced to abandon his final challenge after 200 miles - 700 miles short of his goal.
Sean, from Cheltenham, Gloucestershire, said: "I was doing a video selfie and I was just running along and I tripped up on a rock and slightly injured my ankle.
"But it really wasn't a serious injury at all - I was stretching and it was okay so I carried on running.
"Over the next few days with my ankle being injured and my knees taking over, some bad terrain and camber issues on the side of the road, all added to pressure building on my knees.
"I did take it easy, things were going well until a few days ago a simple wrong footing sent my body one way and my knee the other.
"Immediate pain. I knew straight away it was game over."
Writing on his blog, Sean added: "It saddens me to say this, but I've finally been defeated by my body.
"I've taken a beating over the years, fractured spine when I got run over in America, stung by jellyfish in the face repeatedly for four months at sea, dislocated shoulders, ribs and thumbs falling down hills etc, but I have always somehow managed to carry on.
"This time however things haven't gone so well."
Sean's Great British Triathlon began in 2008 when he cycled 969 miles from Land's End to John O'Groats.
He then became the first person to swim the length of the UK last November after covering 900 miles during 135 days at sea from Cornwall to the tip of Scotland.
He began his final leg on August 9 and ran along the north coast of Scotland and made it to Loch Ness before conceding defeat.
Sean, a photographer, said he plans to re-attempt the third leg next May.
