Great products, even better support staff!
I Had a free 20 minute consult with Stu. We made a fueling/hydration plan. I wanted to make sure before ordering more if I liked the product. I used the flow gel, 30 gm gels, “1000” effervescent tabs and loved them all. Easy to follow and tasted great! It’s all a neutral flavor so you don’t get tired of them and look forward to making a plan for my first full IM distance race.

Precision!
Dopo aver provato numerosi gel e polveri, ho utilizzato Precision Fuel & Hydration negli ultimi 70.3 e sono diventati i miei punti di riferimento per il buon sapore, la facile digeribilità sia dei gel che degli elettroliti e per il fantastico supporto e il piano personalizzato! Eccellenti

Bonne compagnie d'hydratation!
Le goût des gels et ils excellents et me supporte très bien lors de mes entraînements. Les pastilles se transportent facilement pour et permettent de recharger nos électrolytes en pleine séance lorsque nécessaire. Je recommande fortement cette compagnie.
