Intrepid students from the College of West Anglia camped overnight on the top of Snowdon as part of fundraising efforts to support a military charity.
They climbed the Welsh peak to its 3,560ft summit, and stayed overnight before setting off at 4.30am and tackling four more mountains of 3,000ft by 2.30pm. The college team had to endure winds gusting up to 45mph as they camped at the top of Snowdon.
All of those who took part, five students accompanied by a member of staff, are uniformed services students at the college.
Their efforts raised £1,170.89 which they have presented to the Norfolk branch of the Royal Marines Association.
The amount raised, which also included a sponsored head shave, was presented to Marines branch chairman Fraser Wibberley at one of its monthly meetings in Norwich.
Over the years many students on the uniformed services course have gone on to join the Marines and two of the current staff, Lee Mallott, outdoor activities and uniformed services programme manager, who led the Wales expedition, and John Felmingham, are both former Marines.
Each year the college department selects a military charity to support. This is the first time funds have been raised for the Norfolk branch of the Marines Association.
