Sports Performance Leadership - David Bailey: Beyond Marginal Gains: From British Cycling to World Tour Leadership

Episode 205: In this episode of the Sports Performance Leadership Podcast, hosted by Pete McKnight, we are joined by Dr. David Bailey — an internationally recognised coach, sports scientist, and performance leader whose career spans over two decades across Olympic, corporate, and professional sport.

David is currently Head of Performance Support with a World Tour professional cycling team, where he leads multidisciplinary sports science and performance teams competing at the highest level. Over the past ten years, he has helped drive innovation and integration across physiology, nutrition, technology, and data — guiding athletes and staff towards sustained world-class performance.

Before his move into cycling, David was a Senior Research Scientist at Nestlé, responsible for global sports nutrition research for PowerBar, and previously a sports physiologist with the English Institute of Sport across three Olympic cycles — Athens, Beijing, and London — supporting athletes in cycling, triathlon, and other endurance sports.

With a PhD in Exercise and Sport Nutrition from Loughborough University and more than 50 peer-reviewed publications, David continues to shape the evolution of applied sports science and performance leadership — bridging the gap between research, technology, and real-world performance.

In this conversation, David and Pete explore the art and science of performance management — from the “aggregation of marginal gains” to the power of reflection, collaboration, and human-centred leadership in complex, high-pressure environments.

Topics Discussed:

• David’s journey from academic research to elite performance leadership

• The real meaning behind “aggregation of marginal gains”

• Balancing data-driven insights with human-centred leadership

• Lessons from Olympic sport, corporate R&D, and World Tour cycling

• The future of performance leadership in the age of AI and technology
