Do you suffer from cramps? Do you perform poorly when running in the heat? Ever experienced a kind of malaise that leaves you unable to hold your pace? Have you ever dropped out of a race or ended up in the medical tent? Do you come home from runs drenched in sweat? Do you find salt stains on your running gear?
If you answered yes to any of these questions, you may need to learn more about how to hydrate for running. Well, you’re in luck! Today’s episode is all about hydration. My guest today is an expert on this topic. Andy Blow is a Sports Scientist and the founder of Precision Fuel & Hydration.
Andy was formerly an elite-level triathlete who can count a couple of top-10 IRONMAN finishes and an Xterra Age-Group World title to his name.

Hydration for Runners
Hydration is a big deal for runners. If you’re not careful, you could end up feeling really sick and not performing at your best. That’s why Andy Blow, the founder of Precision Fuel and Hydration, is here to help. He was once a professional triathlete and knows all too well the dangers of not being properly hydrated.
What is hyponatremia?
Hyponatremia is a medical term for when the levels of sodium in your blood are too low. This can cause a number of symptoms like cramping, feeling lightheaded, and being really tired. Andy had these symptoms during races and found that by increasing his salt and sodium intake, he was able to perform better and feel better afterwards.
Why is hydration important for runners?
If you’re not hydrated, your body can’t perform at its best. Dehydration can lead to a drop in your blood volume, which means your body can’t regulate your blood pressure or keep blood flowing to your gut. This can make it hard to eat and can cause digestive issues, making it even harder to perform. In fact, a study of ultra-runners showed that the number one reason people didn’t finish a race was because of digestive problems, and that these problems were made worse by losing too much fluid during the race.
How can you tell if you’re dehydrated?
The easiest way to figure out if you’re dehydrated is to weigh yourself before and after a run. The difference in weight will show how much fluid you lost. It’s important to remember that everyone is different and you may need to try a few different things to find what works best for you.
What should you do to stay hydrated?
The first step is to pay attention to how much fluid and electrolytes you’re taking in before, during, and after your run. Electrolytes are important because they help regulate your fluid levels. Sodium is a particularly important electrolyte, as it’s lost in large amounts in sweat. You can find more information on fluid and electrolyte intake on Precision Hydration’s website.
In conclusion, being properly hydrated is crucial for runners. Not only will it help you perform better, but it will also help you feel better afterwards. If you’re not sure if you’re getting enough fluid, try weighing yourself before and after a run. And don’t forget to pay attention to your electrolyte intake, especially sodium.
