A team of workers from Marks & Spencer are hoping to raise £5,000 for an Island suicide charity.
The eight staff and 11 of their friends and family will climb the three highest peaks in England, Scotland and Wales in 24 hours.
The challenge, in June, will raise money for Isle Stand Up To Suicide, which supports people in crisis.
The team have set up an online page for donations and so far have raised half their target.
