Precision Fuel & Hydration Review: Are The PF Running Gels and Chews Worth It?

I first tried Precision Fuel & Hydration after a couple years of experimenting with different running gels and chews — spoiler alert, I which I had discovered the brand sooner!

What immediately stood out with Precision Fuel was how simple everything felt. No overpowering flavours, no sticky mess and no guessing how much fuel I was actually taking in.

After using their gels and chews consistently in training and races, they’ve become some of the most reliable fuelling products I use.

This review of Precision Fuel gels and chews is based on my experience as a runner who used to be terrified of taking gels!

2026 edit: Precision gels have fuelled many half marathon PBs and my first ever marathon (under 3 hours). These are the best gels. Period.

About Precision Fuel & Hydration

Precision Fuel & Hydration was founded in 2011 by Andy Blow, originally driven by 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 experienced first-hand how difficult it can be to manage hydration in tough race conditions. Like many endurance athletes, he struggled with cramping and performance issues that couldn’t be explained by a generic, one-size-fits-all approach.

Today, Precision Fuel & Hydration is trusted by professional teams and everyday athletes alike. Alongside hydration and electrolyte solutions, the brand now offers a full range of fuelling products — including gels and chews — designed to make endurance fuelling simpler, more tolerable and more effective.

If you follow my running journey on Youtube, you probably already know how much I rate these products.

Precision Fuel PF 30 Chews review

The PF 30 Chews come in packs of two, delivering 30g of carbohydrates per serving.

Texture-wise, they’re really easy to chew and don’t get stuck in your teeth — which might sound like a small thing, but mid-run it actually matters. They’re not sticky, they don’t feel claggy, and they’re easy to eat while moving.

The flavour is very subtle, which is something I personally love. One of the biggest problems I’ve had with other fuelling products is flavour fatigue — after a while, everything starts to taste sickly and unpleasant. With these, I never get that feeling, even when I’m taking on fuel regularly.

I often use the chews before shorter runs if I haven’t eaten, before track sessions, or even just before a race. They sit really well on my stomach, even when taken close to heading out, and that’s probably the biggest reason I keep going back to them.

I like the neutral flavoured chew, but I often reach for the Mint & Lemon flavour which feels really refreshing without being overpowering.

Precision Fuel PF 30 Gel review

Before trying Precision Fuel gels, I genuinely thought gels just weren’t for me. I’d always found them too sweet, too thick, or too difficult to get down without water.

That changed the first time I tried the PF 30 Gel.

The texture is incredibly smooth and not sticky at all. I was honestly surprised by how quickly I could finish one — it went down in seconds, and I didn’t need water with it. That alone made a huge difference to how confident I felt about fuelling mid-run.

The flavour is very mild, almost neutral, with just a hint of citrus. I originally thought I’d miss having a stronger flavour, but it actually makes the gel much easier to tolerate, especially later in a run when your stomach is more sensitive.

Most importantly, I’ve had zero stomach issues with these gels. I’ve now been using them consistently since September 2024 in all of my races (and often in training), and I genuinely believe they’ve played a part in helping me hit new PBs. Fuelling no longer feels stressful or forced — it just fits into the run.

Precision Fuel PF 30 Caffeine Gel review

I’m a big coffee lover, but I’m also quite picky with caffeine products because some caffeine gels can taste bitter or leave a weird aftertaste.

The PF 30 Caffeine Gel is honestly much easier to take than I expected. It has the same smooth texture as the original PF 30 Gel, so it still goes down quickly without feeling sticky. Taste-wise, it’s mild and I don’t notice bitterness, which is the main reason I’d actually use it again.

I keep this one for harder sessions and race day rather than everyday training. If I want a little extra boost in the later stages of a long run or when I’m pushing for a time goal, it’s a really practical option.

How Precision Fuel compares to other running gels

Compared to many other gels and chews I’ve tried, Precision Fuel stands out for being deliberately understated. These products aren’t trying to be exciting or indulgent — they’re designed to work.

If you’ve struggled with overly sweet gels, sticky textures or fuelling products that upset your stomach, Precision Fuel is a much more reliable option that will not cause flavour fatigue and will support your performance rather than affecting it.

Gels vs chews: which should you choose?

If you’re trying to decide between the two, it really comes down to personal preference and how you like to fuel.

I tend to use the chews more often in training or before runs because they feel light and flexible. The gels are my go-to for longer runs and races, when I want something quick, smooth, and easy to take on without breaking stride.

The nice thing is that both products work well together, so you don’t feel locked into choosing just one.

Are Precision Fuel & Hydration gels and chews worth it?

For me, yes.

They’re not the cheapest fuelling products available, but they’re some of the most reliable I’ve used. I trust them, my stomach tolerates them, and they’ve made fuelling feel far less intimidating — which has had a real impact on my training and racing.

If you’re still trying to find a gel or chew that works for you, or you’ve had issues with fuelling in the past, I genuinely think Precision Fuel & Hydration is worth trying.
