discovered a mania for exercise that I have sadly, never located since. I was running 12km for kicks. Swimming 50 lengths for jokes. Doing 90 minutes of hot yoga and wanting more. I have never been more toned. I would head out for a run wanting to rip someone’s head off, or hating on myself with the power of a thousand suns, and come back feeling Gandhi serene. A runner called Monte Davis summed it up beautifully in the 1970s, when he said, ‘It’s hard to run and feel sorry for yourself at the same time.
