As a charity, Help for Heroes has many fundraisers and supporters who are willing to go the extra mile (or 26.2) for what they believe in.
Whether it is baking, climbing, trekking or holding a sponsored silence. Each challenge brings in essential funds for our wounded, injured and sick Servicemen and women, and enables them to receive the necessary assistance on their recovery journeys.
For one supporter, however, a gruelling challenge has thrown up the opportunity to do something special.
Terry Bradbury, a former sailor from Stoke, will step back inside a warship for the first time in two-decades next month as part of the Virgin London Marathon.
Confused? Don't be. Of course, the route through the capital will take participants past the iconic HMS Belfast, but Terry will be donning a unique fancy dress costume.
The 52-year-old has made a Destroyer outfit out of cardboard, complete with a radar, and turret gun. It also proudly bears the D-97 coding of HMS Edinburgh, a type-42 vessel on which Terry served for several years.
Now the owner of a window cleaning company, the fitness enthusiast is fuelled by a desire to help his "brothers and sisters", Terry said: "I was medically discharged from the Navy because of an injury, and although I never needed any assistance, I know people who have.
"Help for Heroes means a lot to me, and I think it is great that current and former Service Personnel are getting help and the right support."
If the fundraising aspect wasn't a big enough spur, Terry also has his sights set on a Guinness World Record.
He is aiming to complete the circuit in under 4hrs 20minutes, which is the current leading time dressed in similar fancy-dress and is confident he will set a time near the benchmark.
"The training for the marathon has gone really well. I have had a couple of injuries along the way, but I have taken part in several long-distance races as well as other events.
"I think I will definitely get around the course, but I have never dressed as a warship before!"
The 2018 Virgin Money London Marathon will take place on Sunday, April 23.
