It's that time again. It's 'Carabine Promotions Annual Charity Fundraiser Fun Run Run for Charity.' It's a big event (and an even bigger sign) as the whole of Carabine's staff take to the country park wearing lycra to raise money for homeless people.
This year Matthew is determined not to end up on the wall of 'Disgraces to the Company'. Intimidatingly athletic co-worker Lucy looks a surefire bet to win until a startling revelation from Tom's childhood suggests that he might just be the man to coach Matthew to victory. He might be... but only if he can tear himself away from his one-man quest to eat a food from every country around the world.
Ben's hungry too. When a trip to the farmers' market ends in Ben becoming a murderer (of a chicken), he packs in his obsession with meat. He's going cold turkey and refusing chilled poultry of any kind, but as the full meat withdrawal sets in he finds himself struggling with his conscience to eat any living food, be it fruit, fish or vegetable and the inevitable hunger sends him slightly mad.
Carabine backs Lucy to win and, as he works on her training, she gloats round the office. Matthew wallows in the knowledge that last place looks a certainty once again.
Tom's gluttony grows larger and so does his belly, but will he remember the glory days of his childhood athletics, get off the couch, step into the tracksuit once again and help his best friend Matthew beat his greatest office rival?
