Edinburgh boxer John McCallum is set to take part in an endurance run in aid of Help for Heroes.
Twins Damian and Joseph Duffin, 25, from Bathgate, who are former Royal Marine Reserves, have organised the 250-mile run at Bathgate Sports Centre.
The event will see a group of clients from their company Experience Exercise collectively complete the trek on Sunday.
John, 22, who lives in Southside, said: “Damian and Joseph asked me to do the run and I jumped at the chance. It’s good to give something back.”
