Noor Aziz, 49

Founder of Purpose Performance Wear

Height: 1.77m Weight: 66kg

Exercise regimen: My training varies from six to nine times a week. It's swimming on Mondays, double sessions of cycling and running on Tuesdays and Thursdays and single runs or riding sessions the other days. Weekends are my long training rides and runs.

Diet: I've cut out rice and unnecessary carbs and started taking in more protein and fats. I'm still a long way from a true LCHF (low-carb, high-fat) diet. Except for race day and a few days before that, I don't eat breakfast. My first meal of the day is lunch. Dinner is usually after training. I snack on nuts.
