The winter mountaineering challenge will see participants walk through snow and winter weather to the 1,344m (4,408ft) summit of Ben Nevis.

Taking place between 24 and 27 March 2011, the event organiser UK Outdoor Pursuits will teach essential skills in navigation, rope work and emergency procedures, but participants need to ensure that they're fit enough to take part in the first place.

There's a choice of more than 20 charities to raise money for, including the National Osteoporosis Society. The booking fee is £117.50 and minimum sponsorship is £580.
