A soldier is hoping to break a world record this weekend by running the London Marathon wearing a full bomb disposal kit.
Doug Fitzsimon, a Staff Sergeant with the 11 Explosive Ordnance Disposal Regiment, aims to complete the run in under six and a half hours.
He is running the London marathon to raise money for military charity - Tickets for Troops.
Staff Sergeant Fitzsimon said he is apprehensive about what is ahead, but he is also ready for the challenge.
"It drains every muscle - from the helmet on the neck... all through the back..."
"It's not just tiring on the body, but on the mind as well."
The bomb disposal kit weighs more than five stone, massively restricting movement.
"It is perfect [for bomb disposal], that's why the Army has it. However, it is certainly not ideal for running marathons."
But is not the first time Staff Sergeant Fitzsimon is taking the kit on a run. At the beginning of April Doug completed the Manchester marathon in under 9 hours.
"The biggest thing I am thinking about is getting to that finishing line and taking all this off."
