Are your hormones hijacking your training? If you've ever felt off during certain weeks of your cycle and wondered if your nutrition needs to change, you're not alone.

This week, we're tackling one of the most common questions from female triathletes: should you be fuelling differently during your period? With new research emerging, it's time to bust some myths and cut through the confusion.

You'll learn:

• What the science actually says about performance across the menstrual cycle

• Why your luteal and follicular phases might affect more than just your mood

• Practical tips to help you tweak your nutrition when (and if) you need to

This episode will help you feel more confident and in control of your body, your training and your nutrition, no matter where you are in your cycle.
