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!"

Game Changer
Flow 300 and the soft flask have been a game changer for my Ultra fueling, no more individual packets to have to open and store, no more sticky fingers and no remembering how many carbs I have taken in because the flask delivers the fuel easily (just drink it) and shows you how many carbs you have digested which also means no more needing to count how many gels you need between check points, just grab a flask with 300g of carbs and go.

Best if you have gut issues with other brands
Precision Fuel & Hydration gels are hands down the best I’ve ever used since getting into running. The consistency, flavor, and how easy they go down during long runs are unmatched. I’ve tried just about everything out there, and nothing keeps my energy and stomach this stable — especially during high mileage weeks. These gels are a huge part of my prep for my upcoming 100-miler. Can’t recommend them enough.
