Microplastics & Performance: What Every Triathlete Should Know

There’s a sneaky, microscopic invader you're probably overlooking and in this episode, I'm joined by Dr. Heather Leslie, one of the world's leading researchers on microplastics, to shed some light on this topic that's both mind-blowing and crucial for anyone looking to optimise their performance and health.

Dr. Leslie is a renowned researcher specialising in plastic and chemical pollution and gained international recognition for her groundbreaking discovery of microplastics in the human bloodstream. In 2024, she established an independent consulting and research company based in Amsterdam.

During our conversation, we explore what microplastics are, how they get into our systems, their potential impact on our health and performance and most importantly, what we as triathletes can do to reduce our exposure.

True athletic excellence comes from addressing not just the obvious aspects of training, but also the subtle factors that influence our performance. In the case of microplastics, small changes to your daily nutrition and lifestyle choices can compound into significant benefits for both your performance on the race course and your long-term health.
