  Dr Kyle works out the precise dietary requirements to support my training while my performance chef Jameel Austin does the shopping and makes the meals to ensure I implement that. Everything I put into my body is cooked by Jameel. He also works in a restaurant as a pastry chef – that’s not a food on my menu – but he comes to our house every Monday and Thursday to prepare the meals.

  We also do an eight-day coffee fast before races. A coffee about three hours before the race should then have more impact. Regular blood-work informs whether any supplements are recommended by Dr Kyle. Supplements that I might have at different times of the year include vitamin D, omega-3 or beta-alanine.

  Like most runners now in almost every distance and endurance sport, I will also take sodium bicarbonate before a race, but I never bother in training. Sodium bicarbonate is essentially baking soda and has long been known to buffer hydrogen ions and thus delay muscle fatigue. Its usage, however, has increased over recent years after it was produced in a gel that helps to bypass the gut and thus reduce the risk of gastro issues.
