Number 1 go to for fuelling
Started off with trying out a personalised fuelling pack and straight away everything in the pack was just what I needed. No stomach issues with the gels and as a very sweaty person the 1000/1500 tablets have kept me fully hydrated and away from any cramps! I have tried so many gels and brands but PH&F will be my number 1 go to for all my training and London Marathon in April!

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
