Cornish trio prepare for US cycle challenge
Two marines and a paramedic from Cornwall are hoping to cycle more than 3,000 miles across the US in 17 days.
The trio includes Wayne Davey, one of the Scilly Boys, a team of four whose vessel capsized during an Atlantic rowing record attempt in 2008.
Their plan is to cycle about 3,100 miles (almost 5,000km) across the country.
Mr Davey said each member of the group "would have to cycle about 185 miles a day".
The riders - Mr Davey and marines Justin Morgan and Damian Barnes - will be cycling from San Diego to New York.
The charity mission will also see the three cyclists scaling the Rocky Mountains.
Mr Davey said: "We are all riding together and not in a relay, so it's going to be physical."
The charities the cyclists are raising money for include Little Harbour, which is the new children's hospice in Cornwall, the Cornwall Air Ambulance and the Royal Marines' Benevolent Fund.
