The Journey of an Ultra Marathoner and Dietitian: An Interview with Renee McGregor

Business of Endurance

In this episode, we’re joined by Renee McGregor, a leading sports dietitian, ultra-runner, and expert in eating disorders, particularly in athletes. Renee has spent years bridging the gap between nutrition and endurance sports, working with Olympians and amateur athletes alike to help them fuel their bodies for peak performance. In today’s conversation, we’ll dive deep into her journey—how she became a dietitian, the lessons she's learned from her own running experiences, and how she helps others avoid common pitfalls in nutrition, like underfueling and the dangers of Relative Energy Deficiency in Sport (RED-S). We’ll also explore how to balance proper nutrition with the high demands of endurance training, her thoughts on the rise of personalised nutrition through tech, and why mental health plays such a crucial role in an athlete’s well-being. Whether you’re an endurance athlete or just someone looking to optimise your health, this episode will provide you with actionable insights on longevity, performance, and finding balance.
