If athletes know their body, we ask questions around, do you ever see white salt marks on your skin?

Do you get many muscle cramps?

Do you feel your sweat rates, low, moderate, high or very high?

And in that picture, we can make a rough and ready estimate, which is not as good as having an actual sweat test.

But it's a vast amount better than just shooting in the dark, which is what people

do most of the time.

That Traathlon's show, the podcast presented by

Scientific Triathlon.com. I'm your host Michael, and I'm a bit under the weather today with a bit of a cold as is typical

for a Finnish July which is when I record this intro but it's all good because the interview

that we have is long so I'll keep it short and sweet with this intro. My guest today is

Andy Blow who is the founder of precision hydration,

a company that creates electrolyte solutions that triathletes can use and endurance athletes can

use to get their electrolytes that they need based on their individual requirements. And Andy is a former elite triathlet

himself and essentially he scratched his own itch after suffering a lot from cramping and

just lack of sodium as it turns out, especially in long-course racing.

So we'll talk about things like why sodium is such a critical component of your hydration strategy and the massive variance in sodium requirements between individuals

that results in there being no easy one-size-fits-all solution.

However, precision hydration has a free online sweat test that you can take to determine with good accuracy

what your own individual sodium needs are.

And we, of course, the bulk of the interview is actually how to take that knowledge into practice and apply this in your hydration, in training and racing, and in your hydration loading, if I can call it that, before races and all sorts of other things.

So I hope you enjoy this interview.

Let's jump in and meet Andy Blow.
