Bella Mackie joins us this week to talk about her new book, the Sunday Times bestseller Jog On, which tells the story of how running helped her address mental health issues during the most challenging time of her life. As well as being thoughtful and empathetic, Bella is also irreverent and self-deprecating. Her advice includes tips on being a supportive friend, and finding hope during bleak times - plus the invaluable: 'Always be jazzy.'
