Following the success of last year’s event, a team of RAF Police and their military working dogs from RAF Lyneham will go on a sponsored march in aid of Help for Heroes and Children’s Hospice South West charities on Saturday.

Each team member will carry a 15kg rucksack and a replica L85 rifle.

They will leave Tedworth House in Tidworth at 3am and follow a designated route to RAF Lyneham. They are hoping to complete the march in a record 10 hours.

Tedworth House was chosen as a starting point because it will be the site of the main H4H recovery centre in Wiltshire.

The walkers hope to raise money for the two major charities through sponsorship and collections from the public along the route.
