Episode One : The Greatest Show on Earth

Paralympian Olivia Breen offers a candid insight into what it's like being an elite athlete preparing for one of the biggest sporting events in the world. Each week she's joined by two of her fellow elite athletes to discuss the highs, the lows, the pressure, the joy - and what their lives are like outside of sport too. This week Olivia chats to three-time Paralympic champion Aled Sion Davies about how London 2012 changed both his sporting career and attitude towards his disability, while shot put world champion Sabrina Fortune reacts to being selected for the Paris Paralympics.
