Former Royal Marine Lee Spencer, who lost his leg in an accident, has had to call off part of his historic triathlon attempt due to bad weather.
'The Rowing Marine' was meant to begin his 'Triathlon of Great Britain' challenge - his unique attempt has never been done before.
He planned to swim the English Channel, before cycling the length of the country, stopping en route to climb the highest peaks of England and Wales.
The final leg of the triathlon would see the veteran, who cannot run due to a severely damaged knee, undertake a marathon on foot.
At the beginning of his triathlon attempt, his swim was hampered by difficult conditions and he could only manage part of the journey.
He tweeted: "Some things aren't meant to be, and today I wasn't meant to cross the channel.
"Due to tide and sea conditions that were out of my ability range, I was struggling to maintain forward momentum. I only managed less than half a mile in the 3rd hour," he added.
