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!"

The best hydration products, and fuelling expertise, I've found
I absolutely love these products. They've helped me to top my half/10mile/10km PB's in the first 2 months of using them.
Not sickly or too salty, great flavour and easy to use.
The support in starting with these from the team at PH has been incredible. I feel like I've got the head start I need to attack my marathon in April.

perfect size for long competition in soft bottles, less waste and less risk of loss
Fast order processing and quite speedy delivery from central EU warehouse.
Great to see these largest gel size. I otherwise used your regular size gels on the mountain bike. Fiddling with them to open while riding made me lose quite a few throughout the season which is not great from so many perspectives in competition situations. So I am looking forward to trying out your soft bottles in a running vest now

Quality product range
Fantastic products. Used for marathon training and will be restocking for the race itself. The electrolyte tablets are fantastic and the range depending on sweat content allow buying to suit. The larger PF90 and flow gel pouches are brilliant for longer runs. Zero stomach issues to report from the pf30, +caffeine, pf90, or flow gel products and the texture is easily palatable.

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.
