Andy Blow on Fueling Smarter, Building a Brand Athletes Trust, and High Carb Fueling
About this episode
Quick note before you press play. This conversation with Andy Blow first aired on Long Run Labs, Jon's podcast about the business of endurance and the outdoor industry. Andy is the co-founder of Precision Fuel and Hydration and one of the most thoughtful people in the sport when it comes to how athletes should actually be fueling. Precision sponsors For the Long Run, but this episode wasn't recorded out of obligation — it was recorded because Andy's story is genuinely worth hearing and there's a lot of tactically useful information in here for anyone who runs long.
If you like going behind the scenes on how the endurance world actually gets built, Long Run Labs is worth finding. Guests include sports marketers from Salomon, Garmin, ASICS, and Amazfit, founders from brands like Ketone IQ and Lagoon, and athletes turned media like Des Linden, Kara Goucher, and Dylan Bowman.
Andy Blow started Precision as a sweat test, not a product. He was a triathlete who kept ending up in the medical tent with hyponatremia in hot races, figured out he was a heavy sodium sweater, changed his approach, and built a company around the idea that electrolyte loss is individual and most athletes have no idea what their actual numbers are. Fifteen years later, Precision is crewing eleven athletes at Western States and working with Rachel Entrekin on the data that backed her Cocodona course record.
This conversation covers the science and the business in equal measure.
