A team from a film and media company is to travel the length of the River Severn to raise funds for charities.
The source to sea challenge will see the group from Bewdley-based DRPG kayak, run and cycle the 220-mile (354 km) route from the heights of Plynlimon to the Bristol Channel.
DRPG chief executive Dale Parmenter, who is taking part, said he was inspired by BBC Children in Need and hoped to raise £20,000 for four charities.
"Like most great ideas this one started in the pub, I wanted to do something big for our 45th [anniversary] and that seemed like a great idea," he said.
"The River Severn has played a big part in my life."
"One of my first films I ever made was on the Severn. I used to row as well. My family came up from France on the troves about 300 years ago and I went to school by it, so I thought 'this is fitting let's do the whole thing'."
DRPG supports companies with their internal and external communications and said it had worked with the likes of Tesco, Lloyds Bank and JLR, among others.
Charities set to benefit from the challenge are the River Severn Trust, award-making foundation Meeting Needs, the King's Trust, and Wheels for All, which champions inclusive cycling.
Mr Parmenter said the group had been training "a few times a week", practising a few of the disciplines.
"There's a bit of an age difference between us so I think there's going to be a bit of competition," he joked.
