64: Elevated Blood Sugars in Endurance Athletes: Is It Pre-Diabetes or Under-Fueling?

Blood sugar has become a hot topic, but what does it actually mean for endurance athletes? Should you be worried about glucose spikes, or are they simply part of fueling well for performance?

In this episode of Endurance Eats, Alex Larson and Team ALN dives into the science of blood sugar regulation in endurance athletes. They explore how exercise changes glucose responses, why blood sugar isn't something to fear, and how athletes can make sense of the growing popularity of continuous glucose monitors (CGMs).

You'll also learn when blood sugar data can be useful, when it can be misleading, and why context matters when interpreting glucose trends. Rather than chasing perfectly flat blood sugar, this conversation highlights how strategic fueling supports both performance and overall health.

Whether you're curious about CGMs, managing energy during long training sessions, or simply want a better understanding of how your body uses carbohydrates, this episode offers practical, evidence-based guidance.
