I am a believer!
I am preparing for the Dopey Challenge at Disney World. I was looking for a new fueling plan. The one I use now always seems to come up short and I end up hitting a wall and cramping at the end in past races. I decided to try Precision Hydration and I am glad I did. I received my custom trial kit and used it for one of my long training runs. I am glad I made the change. No cramping at all! Also, those carbs hit different. Everytime I took down one of the gels, I felt like I had hit the power up ...

Gels/Salt/Powder are all awesome!
The products are awesome. Very easy on my stomach and easy to consume on hard effort runs. I also appreciate the hand written notes. Please keep that up. I think that’s awesome you take the time to write something. That’s really cool.

Maximize Carb Intake
Incredibly easy to consume because there’s just enough flavor to keep you interested but not so much to overwhelm

Why you need Electrolyte Capsules
Totally changes my racing when I completed the sweet test. Tried the Electrolyte Capsules during Ironman Knokke and never suffered any cramps. Wish I had known about them earlier on in my racing.

The products I’ll stick with
These are the first products I’ve used that haven’t left my stomach hurting. Small details such as the gels having a little attachment so the ripped “lid” doesn’t come away, or the packaging being easy to rip on the move or with gloves on. The taste is great and most importantly for me, it’s all vegan.
