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!"

Great products!
Products are great! They sit easily prior to a run and during a run. The flavor is great too! Still not sure exactly what it is, some form of generalized citrus maybe, but its great. Not overpowering, not too sweet. I would recommend the gel flow and the carb drink the most.
The individual gel packs are great pre-run, but I have thr hardest time opening them completely during a run. The top is nice that it stays attached, but doesn't tear off completely.
The gel flow is the way to go. I was ...

Great all rounder
I decided to try Precision for all my fuelling since it is what’s provided on course during Ironman WA. Cannot fault any of the products I’ve tried. They taste great and digest well with me and I plan to continue to use them to support my training/racing.

If you want the most of your training you need to try PF
Honestly, PF is next level. Their products are great, their entire system stacks so well together, and what's even better is their service. Their help in building a fueling plan was so educational, and has made a big impact to my performance on the bike.

New go-to run nutrition
I’ve been looking for something like this forever! A relatively affordable gel that I can buy and bulk and use from a reusable flask. Its texture and taste are inoffensive and a serving has more carbs than a lot of gels on the market. I have already reordered. I plan to continue to train with this gel and use it in my upcoming race!

Product review
Absolutely great taste and I’d never experienced stomach issues.
Perfect portion sizes. So I can easily combine caffeine gels with chew bars or something to get the overall amount of carbs and calories.

300g pouches
Brilliant and ideal to put it straight into the flow flask, so much easier than trying to rip open gels. Tastes good too.
I’ll be buying more products during my Ironman training
