A POLICEMAN is preparing to undertake the beat of a lifetime along two Roman walls.

Sergeant Kevin Sinclair, part of the Feltham North Safer Neighbourhood Team, will walk 110 miles along the lengths of the Antonine Wall and Hadrian's Wall for charity, starting on August 2.

The money he raises will be split between Help for Heroes and The Army Target Shooting Club (ATSC).

To make it even harder, Sgt Sinclair will be completing the march wearing 30kg of British Army desert fighting kit, including body armour, a water pack, desert assault vest and a helmet with goggles. Instead of a rifle, he will carry a Help for Heroes flag.

His team mates on the trek are also planning to wear weighty kit.

Sgt Sinclair said: "I fully appreciate what our armed forces are doing. I know it will hurt completing this march, but it will be worth it."

The walk is being organised by Sergeant Angie Sowerby from the Royal Logistic Corp at Bulford in Wiltshire. Thirty per cent of the money raised will go to the ATSC, which is converting accommodation at Bisley Camp shooting centre to cater for injured soldiers.
