Charity challenger Wayne Ingram is spending seven days and nights in the confines of a life raft with just one day’s worth of rations.

The fundraising initiative and scientific experiment began yesterday at Portland Marina, Portland Harbour, Dorset.

Wayne tweeted this at 8am this morning: ‘Morn folks, cold, bumpy night but huddled down with a space blanket. Very thirsty so will start on my water supply today, bring in the rain’

The twofold exercise aims to raise money for Great Ormond Street Hospital families centre, and secondly to allow Professor Mike Tipton and his team at Portsmouth University conduct experiments on Wayne.

Professor Tipton and his team hope to gain valuable information from the survival challenge.

Wayne has only have a small grab bag on board with him, containing a small amount of clothing and just one day’s food and water – forcing him to survive the remainder.

He added: ‘The information my body generates before, during and after will then allow his team to understand how one copes in a survival situation, potentially allowing others caught within a sea rescue, or mountain rescue to make the right decision, allowing them to survive.

‘This has never been attempted before.’
