Precision Fuel gels and chews review from a runner’s perspective

A few months ago, I decided to order some Precision Fuel gels and chews to see what the hype was all about. Here’s my honest, unsponsored Precision Fuel and Hydration review from a runner’s point of view.

About Precision Fuel & Hydration

Founded in 2011 by Andy Blow, Precision Fuel and Hydration was born from a personal mission to improve fuelling and hydration strategies for endurance athletes.

With a background in Sport and Exercise Science and a successful triathlon career, Andy faced challenges managing hydration in tough race conditions, which led to cramping and other issues.

His search for better solutions led him to Dr Raj Jutley, a heart surgeon who introduced him to Sweat Testing. This revealed how much athletes can vary in their sweat and sodium losses, proving that a one size fits all approach simply does not work.

Together they developed Precision Hydration, which started with patented Sweat Testing and electrolytes.

Today, the company is trusted by professional teams and everyday athletes alike, offering a full range of fuelling products designed to optimise performance.

Unsponsored review of Precision Fuel energy gels and chews

Here’s what I’ve tried from Precision Fuel and Hydration and exactly what I think. If you follow my running journey on Youtube, you probably already know how much I rate these products.

PF 30 Chew review

These energy chews are ideal for fuelling on the go, with a high carb to weight ratio. Each pack contains two chews with a total of 30g of carbs.

They are available in two flavours: Original with a subtle citrus taste and Mint and Lemon which is slightly stronger.

There are no artificial ingredients and these chews contain no electrolytes or caffeine.

Energy chews are probably the fuelling product I use the most in my training. I will have some before a short morning run if I have not eaten breakfast, before a track session or even before a race.

What I love most about the PF Chews, and Precision Fuel in general, is that I do not experience any flavour fatigue. The subtle taste means I never get sick of them.

The texture is also spot on. They are not too sticky, easy to chew and do not get stuck in my teeth unlike other brands I have tried.

Most importantly, they sit well on my stomach. Even if I have them right before heading out for a run, I never feel nauseous or uncomfortable. As someone who can be quite nervous about fuelling before a run, these chews have really earned my trust.

I like both flavours, though I have a slight preference for the Mint and Lemon which tastes really refreshing.

PF 30 Gel review

Each PF 30 Gel contains 30g of carbs with a 2 to 1 glucose to fructose ratio to support fast absorption. They come in a neutral Original flavour with just a hint of citrus.

The formula is Informed Sport certified and free from artificial ingredients.

I have always struggled to take on fuel during long runs and I used to take ages to finish a gel. I had heard so much positive feedback about the PF 30 gels that I decided to try them.

The first time I had one, I could not believe how easily it went down. I finished it in seconds without needing any water because the texture is so smooth and not sticky at all.

I originally thought I would not enjoy a gel without a strong flavour but it actually works better for me.

I also had zero stomach issues and it was the first time I actually enjoyed taking a gel mid run. As I write this post, I am just starting a half marathon training block and I will be using PF 30 gels throughout my training and on race day.

I already know I will fuel much better this time than in previous races.

2025 edit: I’ve now been using these gels in all my half marathon races since September 2024, and there’s no doubt in my mind that they’ve played a big role in all my PBs!

PF 30 Caffeine Gel review

This gel has the same carb content and texture as the original, with 30g of carbs and a 2 to 1 glucose to fructose ratio. It is also Informed Sport certified.

The only difference is that it contains 100mg of caffeine per serving.

I only recently tried the caffeine version as I am considering using it during my half marathon. I am used to caffeine as a coffee lover and I had no issues with it.

There was no bitter aftertaste at all. In fact, I would not have known it contained caffeine if it was not printed on the packet.

Final words

To conclude, I’m really glad that I decided to try Precision Fuel gels and chews and I get why so many endurance athletes rely on these products.

If you’re getting sick of gels that taste too sweet or are still looking for something that your stomach can handle, I can only recommend giving Precision Fuel and Hydration a go!
