Andy Blow Precision Hydration

Andy Blow is one of the first people I call if I want to nerd out on optimizing my nutrition and hydration for training and racing. He is a Sports Scientist and the co-founder of Precision Fuel & Hydration.

Andy Blow is a Sports Scientist with a degree in Sports and Exercise Science from the University of Bath. An expert in sweat, dehydration and cramping, Andy previously worked as the Team Sports Scientist for the Benetton and Renault Formula 1 teams and remains an adviser to the Porsche Human Performance Centre.

An elite level triathlete in his younger days, Andy has finished in the top-10 of Ironman and IM 70.3 races, as well as winning an Xterra World title. It was Andy’s own struggles with cramp and hydration that led to him specializing in electrolyte replenishment and founding Precision Fuel & Hydration. Andy is a leading figure in the world of sports hydration and has worked alongside Dr Raj Jutley, as well as other top sports scientists, to co-author a number of studies and books.
