09 - Why Fueling Isn’t One-Size-Fits-All: Personal Hydration Strategies for Athletes with Andy Blow

About this episode

The episode discusses personalized hydration strategies for athletes, emphasizing the importance of understanding sweat composition.

From trial and error to precision, this episode unpacks why knowing how salty a sweater you are can unlock better fueling, hydration, and performance. Episode Description: Most runners know when their legs are tired, when their heart rate is higher than they'd like, and when their watch disagrees with reality, but far fewer know what’s actually happening in their sweat. And yet, hidden in those grains of salt is a story about performance, cramping, gut trouble, bonking, and why two athletes with identical race fuel and hydration plans can do the same race with wildly different outcomes. In this episode of Legwork, Matt and Molly talk with Andy Blow — endurance athlete, sports scientist, and founder of Precision Fuel & Hydration, to explore the messy, fascinating world of electrolytes. From Andy’s own battles with hypernatremia to the science behind sweat testing, the conversation pulls apart the myths, marketing, and misunderstandings that keep athletes guessing. It’s a journey from personal experiment to practical insight, showing how something as simple as knowing your sweat composition can reshape your entire fueling strategy and help you be a more informed athlete…
