Only 10 people took part in the British Red Cross's first Disaster Response Challenge, well below the target of 50 participants.
The 10 were taken to a military base in Hampshire for three days where they had to respond to a hypothetical earthquake.
They learned skills such as skinning rabbits, building refugee camps, and basic first aid under the guidance of Red Cross staff with experience of disaster zones. Each participant paid £50 to enter and pledged to raise £450 through sponsorship. The charity had hoped to attract up to 50 entrants and raise £25,000 but corporate support proved non-existent.
"We hope that through the contacts we made this time we will be in a better position to attract companies," said senior fundraiser Rebecca Payne.
Despite the slow start, Payne said the Red Cross planned to stage three similar events each year.
