Don't let hydration continue to slow you down.

Andy Blow, founder of Precision Hydration, learned about the impact hydration issues can have on performance the hard way: by spending time in the medical tent during multiple races in hot, humid conditions.

 But, through a lot of research and plenty of trial and error, Andy uncovered some important truths about the science of hydration and has been working with coaches and athletes to spread his knowledge ever since.

He has implemented his knowledge at the highest levels of sport. First through his role as Team Sports Scientist at the Renault and Benetton Formula One racing teams and then through his work with elite athletes in pro sports teams in the NFL, NBA, MLB, NHL, Premier League and beyond, as well as in endurance sports like triathlon, cycling and ultra running.

You should consider this course if you're a coach who wants to help athletes avoid common hydration mistakes during training and racing. 

Athletes who frequently run into GI and cramping issues during activity or just want to improve their performance can benefit from this course too.

By the end of the course, students will be familiar with the complicated history of hydration science, have a good understanding of the science of hydration for endurance athletes, and also have the tools and know-how to build personalized hydration strategies for training and racing.

Founder, Precision Hydration

Andy Blow has a degree in Sport and Exercise Science from the University of Bath and was once the Team Sports Scientist for the Renault and Benetton Formula One racing teams. He has a few top 10 IRONMAN and IRONMAN 70.3 finishes and an XTERRA World Age Group title to his name. He founded Precision Hydration to help athletes solve their hydration issues after suffering from hyponatremia and cramp during his own races in the heat (he's a VERY salty/heavy sweater!). Andy and PH work with a long list of pro sports teams in the NFL, NBA, MLB, NHL, Premier League and beyond, as well as elite and age group athletes in endurance sports like triathlon, cycling and ultra running. These days Andy regularly races swimruns, open water swims and trail runs.
