When selecting a tracking method, aim for simplicity. If you already utilize a training software program such as Training Peaks or Workout Log, check to see if there is an option for logging your food intake. “It’s always nice to be able to view your training and nutrition side-by-side,” says Lentzke.
Dozens of free and paid wellness apps have been created for smartphones, allowing triathletes to log their calorie intake and expenditure on the go. Eley recommends free apps MyFitnessPal, Lose It!, and MyPlate, all of which track calories and macronutrients.
