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!"

SUP ultras
As one of the top endurance standup paddle athletes in the uk iv Been looking for the best way to fuel for these events as, unlike a lot of sports, we constantly use our hands to power us along.
Last year, I raced the non-tidal Thames as a non-stop event. In this, I did the thing that is always advised not to do and try a different brand of gels / fuel! Now, this was going to be a 30-hour event, so having an issue would have been a race killer. So, after 29 hours and winning the event and also ...

Top-Tier Nutrition for Ultra Endurance and Demanding Work
I’ve been using Precision Hydration for training for a 24-hour ultra marathon, and the products have exceeded all expectations. The 30g gels are smooth and easy to digest, the caffeine gels give a clean energy lift, and the 90g gels provide a super convenient hour of fuelling. The 300g flow gels are ideal for long sessions – over 3 hours of consistent energy without any stomach issues.

Flow gel 300 is fire!!
My first experience with Precision Fuel I dove in and got the flow gel 300. I tried it out on a local trail and used it over 5 hours. I’m impressed with how mild and smooth it is with little after taste!! And I got the one way FKT (28 miles) on the trail! Just ordered 5 more and will be using it again for an attempt at the out and back FKT!

Perfect gel for longer race
This gel works super well for a longer race. I did 18 hours taking the gel in combination with electrolytes with no problems or issues in stomach. The taste works fine even after many hours.

Steady Energy for Long Ultras!
Love! These! Gels! Precision Hydration's gels are a game-changer for ultras, particularly at the post-50mile mark when the smooth texture and mild flavour shine at a point when it can be tough getting fuel down. A great option for sustained endurance performance.
