Episode Notes

Andy Blow didn't set out to build a company. He set out to stop ending up in the medical tent. As a triathlete who kept collapsing in the heat, Andy discovered that electrolyte loss is deeply individual, got a sweat test, changed his nutrition, and realized that what he needed didn't exist for other athletes either. Fifteen years later, Precision Fuel and Hydration is one of the most trusted names in endurance sports nutrition, working with elite athletes from Rachel Entriken to Caleb Olson to the Ironman World Championships.

Andy joins Long Run Labs to talk about the science, the business, and everything in between, including what it actually took to survive long enough to build something real.

Jon and Andy chat about:

  • why Andy kept ending up in the medical tent and what it taught him about individual fueling
  • how Precision Fuel and Hydration started as a sweat test, not a product
  • why separating fuel from hydration is the foundation of their entire system
  • the three levers every endurance athlete needs to understand: carbs, fluid, sodium
  • what amateur athletes consistently get wrong about race nutrition
  • the Tim Noakes debate and how to think about high carb fueling
  • Rachel Entriken, Cocodona, and what longitudinal field data actually shows
  • why the business nearly died more than once and what kept it going
  • how their Ironman partnership started with a confrontation with Ironman's legal team
  • building athlete rosters around authenticity, not follower counts
  • the F1 years and what endurance sports can learn from motorsport
  • the future of trail race broadcasting and live data
  • why Andy stepped out of the CEO role in January and what that transition looked like
  • what he believes now that he would have laughed at in 2011
