Precision Fuel & Hydration

Precision Fuel & Hydration provide personalised fuel and hydration products and plans to help athletes optimise performance

Precision Fuel & Hydration was launched in the UK in 2011 by Andy Blow. Andy used to race elite short course triathlon and was a regular podium finisher but struggled in hotter conditions and over longer IRONMAN distances. Determined to find the root cause, he investigated his symptoms of bad cramping and other hydration-related issues, including hyponatremia (low blood sodium levels). While he thought he was hydrating well at the time and following widely accepted advice, he quickly learned his strategy was missing adequate sodium. 

His degree in Sport and Exercise Science aided his process of trial and error to work out exactly how to manage his sodium and fluid levels for sustained performance.

During this period he enlisted the help of respected heart surgeon, Dr Raj Jutley, who explained the large differences in sweat and sodium losses between individuals. Together they looked at how an already established method of Sweat Testing (utilised in Cystic Fibrosis diagnostics) could help identify this discrepancy in athletes, leading to a solution that helped launch Precision Fuel & Hydration.

The company has since gained exclusive access to patented at-rest, non invasive Sweat Testing technology, offered at Sweat Test centers all over the globe, as well as developed hydration products and programs to meet the specific needs of individual athletes.

In the more recent years, Precision Fuel & Hydration branched out into fueling products, offering carbohydrate drinks, gels and chews to help athletes tackle all three levers of performance nutrition: carb, sodium and fluid. Their evidence-based, algorithm-powered online planner provides tailored race strategy plans for how to use these key three components, taking into account sport, goals, weather conditions, estimated sweat losses, etc.
