Precision Fueling
Use the Fuel & Hydration Planner (or the Quick Carb Calculator™ in a pinch) to understand how much fuel you need to perform at your best.
Our range of fuel makes it easy to hit those numbers by telling you how much carbohydrate is in each serving right on the front of the packaging. No complicated nutritional tables to decipher, zero guesswork.
The PF 300 Flow Gel is formulated with a 2:1 glucose to fructose ratio to aid carbohydrate uptake. If you're someone who hasn't gotten on well with gels previously, give ours a try, we'll eat a flip-flop if you're not pleasantly surprised!

"I used to have to squeeze 10 gels into a bottle before a race. Now, I can just pour a Flow Gel into a Flow Bottle. That saves time and the scale on the side helps me keep tabs on what I'm getting on board. It's super efficient and convenient!"

Fuel as a system
I use PH1000 throughout the day as well as in training and racing. It’s been a real game changer for me in hot conditions. Hydration feels much more effective and my body is able to absorb the fluids properly instead of just carrying water in the stomach.

The gels are also very gut-friendly. They’re sweet with a slight fruity taste, but not overly intense – even late in a race they’re still easy to take and don’t become sickl...
