Perhaps the most important thing for those of us who run, for example, to know is just how big a role nutrition plays in race prep. For KJT, it’s so important that she’s enlisted the help of a nutritionist to help get it right.

“In competition, nutrition can be the make or break of your whole schedule. For example, when I was at the World Championships in Doha, the events were in the evening and I didn’t really know what to do. Normally I’d eat breakfast then go to the competition – but in Doha, I’d eat breakfast and then have about seven hours before I’d have to do anything.” Because of that, she says it’s really important to have a nutritional plan for competitions and races.

These days, she has a plan that’s easy for her to follow – she doesn’t have to think about refuelling or worry about when she can eat. “I just go through that with the nutritionist ahead of whatever schedule I’m on.”

For us amateurs, it’s worth getting into a routine that you’re able to stick with. That might mean, for example, getting used to eating an early carb-heavy breakfast two hours before going for a long run, or trying an intermittent fasting routine that sees you eating at the same time every day and planning your workouts around that.
