Eight wounded and injured soldiers and Royal Marines are to set off from Lowestoft tomorrow on an epic 355 mile cycle ride across the country.
But the daunting mission is merely a warm-up for a rather more testing 3,000 mile coast-to-coast challenge across the United States later in the year.
Saturday's endurance ride to St David's Head, Pembrokeshire, will allow the troops and to practise with their support crew over a high-mileage cross-country route before they start their 3,051 mile route from east to west coasts of America as part of the Race Across America (RAAM).
Raising money for Help for Heroes, Team RAAM consists of four double amputees riding in handbikes and four cyclists taking part on upright bikes.
Each rider in the Help for Heroes team has either been wounded on operations or injured training for operations.
They are setting off at 8am from Lowestoft and hope to reach their destination by 3pm.
Taking part are Marine Don Maclean, Sgt Simon Harmer, Staff Sgt Steven Arnold, Marine Joe Townsend, Pvt Steven Richardson, Capt Rupert Smedley and Pvt Jamie Hull.
