The team of 12 took part in The Yorkshire Three Peaks Challenge during Childhood Cancer Awareness Month (CCAM) in September.
The aim of the challenge is to climb the three Yorkshire Dales peaks of Pen-y-Ghent (691 metres), Whernside (728 metres) and Ingleborough (723 metres) within 12 hours.
The team walked 25 miles, climbed and descended 5,500 feet, and achieved all of this in 11 hours and 45 minutes!
In total, the team raised an incredible £22,162 by taking part in the challenge. This total includes a donation of £8,000 from the Barclays Community Investment ‘Pound 4 Pound’ scheme.
Darren Mott, relationship director at Barclays West London, said: “My colleagues and I were invited by CLIC Sargent to visit Paul’s House and to learn about the fantastic work which the team does there.
"We were all extremely moved by the levels of support CLIC Sargent gives to the children and their families, and instantly made the decision to use our annual walking challenge to raise much-needed funds to help continue this great work.
"Spurred on by this goal, we are delighted and proud that our efforts have raised a significant sum to assist with the running of Paul’s House.”
CLIC Sargent Area Fundraising Manager Elizabeth Charing said: “The amount raised by the West London team at Barclays Corporate is truly fantastic, and will make a huge difference to the families whose children are receiving treatment at Great Ormond Street Hospital or University College London Hospital.
"Their donation could pay for over 22 families to stay at Paul’s House for one week!
"The team put all of their efforts into completing the strenuous challenge and achieving the high target that they set for themselves. On behalf of all at CLIC Sargent, I’d like to say a massive thank you to the team and everyone who supported them.”
