Dame Jessica Ennis-Hill is an Olympic heptathlon gold medallist and a three-time world champion. This is a woman who knows what it takes to succeed at the very highest levels, and who has learned to process failure when she doesn’t win. A truly fascinating conversation about the psychology of competitiveness, the importance of loyalty and roots, how injury taught her the value of rest and how losing the 2011 World Championship to a woman who later turned out to be a drugs cheat fuelled Ennis-Hill’s desire to do better.
