INTREPID adventurer Sean Conway has splashed back into Dorset after completing the world’s longest triathlon.

Sean’s ‘Ultra Triathlon’, which started and ended at Lulworth Cove, saw him cover a distance of 4,000 miles unsupported - the equivalent of travelling from London to New Delhi.

The inspiring athlete arrived back in Lulworth on Friday at the end of a mammoth swim, almost three months after he departed on Friday, April 1.

More than 100 supportive members of the public joined Sean’s family to welcome him back with waving banners and plenty of cheering.

“It was the hardest thing I have ever done and I think it will be the hardest thing I ever do,” said Sean.

“To see all these people cheer me in has been massively amazing and it is so nice to have the support of everyone.”

He added that he will be tucking in to “lots of pies and a couple of ales” to gain some weight back now that his test is complete.

Sean’s journey around Britain’s coastline saw him cycle 3,350 miles from Lulworth to Scarborough, run to Brighton and then complete a 390,000 stroke swim to make it back and cross the finish line.

Babette Pinder, Sean’s mother, said: “I want to say bravo and thank the British public for the kindness they have shown to my son along the way.”

Sean has been followed by Discovery Channel cameras throughout his gruelling challenge, with the channel set to air a documentary entitled ‘Sean Conway: On The Edge’ in August.

Fans have been able to track Sean’s progress on social media using the hashtag #GoSeanGo and the adventurer has been providing regular updates and photographs from his journey.
