Catherine Laine, who works as a freelance marketing and media consultant for the alcohol and drug addiction charity, raised £2,500, which has helped to pay for a new service for Jersey children who have parents or older siblings suffering with addiction issues.
Ms Laine and her group took seven days to undertake the challenge, climbing to the summit on day six.
She said: ‘The night that we climbed to the summit was the most difficult thing I have ever done. The trek started at midnight and it took eight hours to climb to the summit.
‘The group and I had a really hard time with altitude sickness – most of us had headaches and felt sick. And quite a number of us hallucinated, myself included.
‘I am delighted I did it. The experience itself was really fun, but gruelling.’
Ms Laine, who is originally from Jersey but currently based in London, said: ‘Silkworth is a wonderful charity close to my heart and it is a pleasure being part of the team.
‘By doing this challenge it gave me an opportunity to do my bit in giving back by helping this vitally needed new programme get off the ground.’
Jason Wyse, chief executive of the charity group, said: ‘Catherine has raised significant funds at a key time for us and the development of our new children’s programme.
‘We have put the funds that have been raised towards developing the literature and funding the first programme, which will run in May, as this is a free service being offered to Islanders aged seven to 12 years old who have a parent or older sibling that suffers with chemical dependency.’
