The annual event, in which teams of IT professionals attempt to climb the three highest mountains in Britain - Ben Nevis, Scafell Pike and Mount Snowden - in 24 hours to raise money for charity, is only six weeks away.
Steve Cook, IT project manager at the Woolwich, is pleased with his team's progress so far. "We have raised the £5,000 we need but we are still going for more," he says. "We raised the money through sponsorship from companies we deal with and individuals - ICL alone gave us £2,000.
"Whenever we can, we are bombarding our work colleagues with demands for money. We have had collections for dress-down days, held sweepstakes on the Grand National, football matches and even on the time and date of the birth of my colleague's baby girl.
"Our main fund-raising event is booked for early July. We are holding a summer ball for around 150 people in which we are incorporating a raffle and a fun casino."
Physical preparations are not being neglected either.
"Training has been good, we have never been so fit," says Cook. "We have all made a concerted effort, mainly training as individuals in the evenings and at weekends, and getting together as a group to do some serious walking whenever we can, usually fortnightly.
"We are in the process of setting up our own Web site, introducing the team, the charity and what we are doing, a thermometer gauge on how the fund-raising is going and a thank-you page for our sponsors."
