In today's programme Clare Balding walks with a group of medics who have all suffered - as they put it - a 'cardiac event'. With good humour and no real restraint, they gather as often as possible to explore new and familiar routes for friendship and health. The group is made up of GPs, hospital doctors, surgeons and a psychiatrist, and their cardiac experiences range from living with angina to surviving a severe heart-attack. They joke about whose turn it is to carry the defibrillator, but the truth is, they don't let their medical conditions get in the way of a good ramble.
