A team from Shepherd Neame is to take part in the Six Peaks Challenge in a bid to raise money for the Water Aid charity.
The team consists of six walkers — chief executive Jonathan Neame; Graeme Craig; Olly Scott; Christian Hamilton; Darren Packman; and Martin Godden. They will be assisted by colleagues Giles Hilton and Stephen Bridgett driving the support vehicle.
They will have to climb the highest peaks in England, Wales, Scotland, Northern Ireland, Eire and the Isle of Man over a long weekend.
It is the equivalent of walking 50 miles, climbing 20,000 feet, driving 1,000 miles and two sea crossings, all packed into 72 hours with no sleep.
Water Aid give some of world's poorest people access to safe water. A gift of just £15 can provide one person in Africa or Asia with a lasting supply of safe, clean water, sanitation and hygiene education.
"It is going to be very tough but we are all excited and motivated by the challenge," said Olly Scott, the most experienced mountain walker of the group.
"This is the first time a brewery has taken part and we are determined to succeed and to raise many thousands for Water Aid. The organisers have even given us the radio call sign 'firkin' which is most appropriate."
