[Podcast] Beyond Race Day: Marco Altini on Smarter Fueling
A conversation with Mikki Williden
A few weeks ago, I had the pleasure of chatting with Mikki about my recent periodized nutrition experiment (covered in detail here). From the show notes:
“Mikki speaks to Marco Altini—data scientist, athlete, and founder of HRV4Training—about his personal and professional exploration into periodised nutrition. Known for his evidence-based insights into heart rate variability and training readiness, Marco has recently turned the lens inward, experimenting with how varying his fuelling strategies around training intensity and adaptation goals can impact performance and recovery.
In this conversation, we dive into what led Marco to shift from a rigid, data-driven approach to one that embraces flexibility, intuition, and physiological feedback. We talk about the science behind carb periodisation, the mindset shifts required to break free from ‘high carb by default,’ and how this approach might offer not just better results—but a more sustainable relationship with training. Whether you’re a high-performing athlete or a time-poor weekend warrior, Marco shares insights that might just change the way you think about fuelling.”
Thank you for listening!
