World's Toughest Row: Four men take on journey of a lifetime
They're raising vital funds for Lyme Disease UK - and will be on the sea for more than a month
A team of four plucky UK rowers are today (11 December) setting off on a journey of a lifetime - rowing 3,000 miles from the Canary Islands to Antigua - all to raise vital money for Lyme Disease UK.
They're known as Team SeaSoar - and will be battling the elements, and of course missing Christmas, for a cause that sticks really close to home for one of them.
From Wiltshire, John Watling is hoping to be 'calling time on Lyme' - after his daughter Yasmin became seriously unwell with the condition after she was bitten by a tick.
He told us: "There's a lot of poor knowledge about the disease, even within the medical fraternity, and even all these years later from her being bitten by the tick, she is still really unwell.
"She's now got a condition called long-term, or chronic, Lyme disease - and it's terribly unpleasant.
"I've written a very special message in my cabin, which I'll be able to see every time I go in there for a rest.
"Yasmin's nickname in our family is 'YaYa' - and what I've written is that she'd like to feel this good.
"But as we finally approach the day - there really is no turning back in all of this! I've told so many people about the challenge that we can't not do this - but as I say, it's all for a great cause.
"Nothing compares to what this is going to be like - at the end of the day, we're crossing the huge ocean.
"But what we do know is that the waves on the Atlantic are going to be huge.
"It's a little bit like surfing - and it's the power behind these waves which will hopefully get us to the other side, and over to Antigua!"
Well, he's not doing it alone, as Niall Brannigan from Southport, Sam Weber from Brighton and Jason Wilder from Nottingham will all be on-board, on their mission to literally get to the other side of the ocean.
Team SeaSoar aren't doing this challenge alone - as every year more than 40 sets of people head onto the ocean in their rowing boats in a race from the Canaries to Antigua.
Millions of pounds have been raised since the challenge has been launched for charities like Lyme Disease UK, because of people like John, Niall, Sam and Jason, who literally train for years before finally reaching this moment.
They've of course named the boat - and it'll be Oardrey who's going to be tasked with safely bringing the squad to the other side.
They'll be rowing for two hours at a time, before resting for another two hours - and working in a loop like this until the very end, estimated to be around the end of January 2025.
The 'oar-some' foursome will lose around 12 kilos of weight on the journey, burning 5,000 calories a day, and drinking 10 litres of water.
Despite the daunting challenge ahead - they all say they're filled with excitement - having worked tirelessly through gruelling training sessions to gear-up for what's set to be a once-in-a-lifetime challenge.
