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!"

I love the gels. So easy to take on and taste so much better than other gels that are on the market. I am also a big fan of the bigger pouches to decant into the flow bottle for longer rides and runs such a good idea. Also delivery is so quick which is always good when I leave it last minute to get my gels before a long run 🤣

Why didnt I know about these sooner ?
Ive struggled for a while with the gels, for digestion, amount to carry and take and taste.
I thought I would give these a try after my 19 miler 2 week before left me almost hitting the wall.
I completed a 20 miler using the 300g flow pouch and the run went so much better. Well as good as a 20 mile run can go. The taste was ok, I wont say it was a taste im going to be wanting for my tea like, but as far as gels go probs best one ive tasted. Didn't have any digestion issues either which is very...

Flow Gel & Chews: Easy Fuel That Works
As someone who trains for long endurance events, fueling properly can make or break a race. Precision Fuel & Hydration’s Flow Gel and Chews have been some of the easiest and most effective fuel sources I’ve used.
The Flow Gel is a game changer compared to traditional gels. The consistency is thinner and smoother, so it goes down easily without needing a lot of water, which is huge during long runs or races. It’s not overly sweet, and it sits well on the stomach even late in a workout when many ...
