Understanding BMR and TDEE

BMR is the number of calories your body needs at rest, while TDEE accounts for activity level. Knowing these numbers helps runners set appropriate calorie targets for weight management and performance.

Why Nutrition Matters for Runners

Proper nutrition fuels performance and aids recovery. Understanding your caloric needs helps prevent fatigue and injuries, ensuring you can train hard and race effectively.

Adjusting Caloric Intake for Training Phases

During base-building, you may need fewer calories, while intensifying training for races requires increased caloric intake. Adjust your diet based on your training cycle to meet your energy needs.

Tips for Running & Endurance

  1. Track your energy levels and adjust calories based on training intensity.
  2. Consider timing your meals around workouts for optimal performance.
  3. Stay hydrated; water intake is as crucial as calorie intake for endurance.
  4. Incorporate strength training to balance your running routine and prevent injuries.
