Training
For increased versatility and resistance, try to add interval training to your routine. For example, you can run at different speeds and slope angles on the treadmill or outdoors. To increase the resistance of your muscles, aim for a higher number of reps rather than heavier loads during your trainings.
Nutrition
Increase the intake of all macronutrients in all the meals you have, particularly of carbohydrates.
Supplementation
Supplementation will make sure that your energy stores last the entire training and that your recovery process is optimised.
