Our story

We launched Precision Hydration in 2011 after years working with elite athletes and technology partners to develop a simple and effective way to help athletes understand and manage their individual hydration needs.

Our Founder, Andy Blow, has a degree in Sport and Exercise Science and was a regular podium finisher in elite short course triathlon racing in his younger days.

But he had some very poor results when racing in the heat and at longer IRONMAN distances. He suffered badly from cramping and had other hydration related issues including hyponatremia (low blood sodium levels, which can have some nasty consequences). This was despite following the widely accepted hydration advice available at the time.

After years of trial and error, he eventually figured out how to effectively manage his individual sodium and fluid intake to maintain his performance.

He was helped significantly in that process by Dr Raj Jutley, a highly respected heart surgeon who introduced him to the concept of Sweat Testing and the huge variance in sweat and sodium losses that can occur from athlete to athlete.

It was through his own search for an effective solution that, with Dr Jutley’s input, the Precision Hydration concept was born.

As things progressed, we got exclusive access to patented Sweat Testing technology that requires no physical effort from the athlete. The technology has a long, credible history as a diagnostic test for Cystic Fibrosis and it's simple, non-invasive, painless and extremely accurate.

We also developed our own range of electrolyte supplements early on because existing products out there were simply not strong enough to meet most serious athletes' needs.

'One-size-fits-all' just doesn't cut it when it comes to hydration. Just look at our team, Andy loses more than three times as much sodium per litre of sweat than Dr Raj!

The team grew, adding Jonny Tye, a paddler who'd won two silver medals at the Junior World Championships before getting involved to drive the development of our products forward.

Word soon started to spread that we were offering a unique, personalized hydration solution. Pretty soon we were providing our services to a growing list of professional sports teams in the English Premier League, International Rugby Union, the NFL, NBA, MLB, NHL, Formula 1 motor racing, MotoGP and Indy Car, as well as elite individuals from the worlds of cycling, running, triathlon and more.

We've even worked with railway workers, firefighters and military service personnel, who are exposed to high levels of heat stress and sweating, helping them maintain performance in even the harshest of environments.

We were now building up such a wealth of data on how athletes sweat that we were able to build a free, algorithm-based questionnaire to deliver personalized hydration advice even if an athlete couldn't make it to one of our Sweat Test Centers. 

Our mission is to give every athlete access to a personalized hydration strategy so that they have the best chance of achieving their goals.
