In this episode of the Tough Girl Podcast, Rebecca shares her journey from the Forest of Dean to the French Alps, balancing elite-level training with everyday life, and the nutrition strategies that help athletes optimise performance, recovery, and health — particularly for women navigating hormonal changes and perimenopause.
We talk race day fuel, strength training, managing limiting beliefs, and why it’s never too late to start a new adventure.
Whether you’re chasing your first trail race or aiming to summit Mont Blanc, Rebecca’s insights will inspire you to push your limits while taking care of your body.
