Fantastic fuel & hydration
Easy to use and great taste
PATRICK FLANAGAN RUNNER
Brilliant products - highly recommend
Been using the precision products a couple of weeks now and couldn’t recommend them enough. The gels taste great, good amount of carbs and sit really well. I am a huge fan of the 90g gel pouch, especially on the early morning sessions when restricted on time to eat before the session. Products have been a great addition to my marathon training leading up to London in April.
Efficient service with quality products
Very helpful with personal input.

I am SO impressed with PH’s website, blog, and products! Their blog is packed FULL of solid knowledge and advice backed by reputable sources and trustworthy science. The fuel and hydration questionnaire created a straightforward plan for nutrition and hydration during my training and upcoming race. I love all of the products I’ve tried so far - the gels, PH1500 electrolyte mix, PH500 effervescent tablets, and the sodium capsules. Their custom sample pack they create for you is the best way to g...
Very happy with my purchase. Really like the taste. Appreciate the different “strength” of electrolytes and will be using stronger ones in the summer.
PH have changed my approach to fuel and hydration
I don't do reviews, but ... I've been using PH 30 gels for a while and have just ordered a new box. I find their taste and texture makes them very easy to consume, without hesitation, compared to those I've used previously, and the free advice about fuelling has allowed me to make fundamental changes to my plans. I've ordered the chews too, as they're more energy dense than those I've been using. I use the electrolyte tablets as well, in my bidons, and they make for a palatable drink. They're ea...

Gel + Tabs = Yes Please
The slight effervescence of the 500mg drink tabs makes the gels goes down absolutely perfectly. I really like the 90g gel for not having to fumble too many gels during longer efforts and it’s helped to ensure I get sufficient carbs in too. Can really feel the difference during and after long runs. Energy levels just feel more sustained overall.

Best decision you will make
Precision Hydration offers the perfect balance for any training programme. The products taste great and do their job brilliantly. I wouldn’t be without them whether training or racing and the improvement in my performance is huge since adding them to my kit bag. The support and resources available regarding planning for specific events is also something I have not found with other products and is yet another reason this company is head and shoulders above the rest. Thanks guys. Keep up the great...

It’s going to be my third time ordering gels and hydration tablets from PH&F and I really enjoy all the products I tried thus far. Gels are just perfect in texture and flavor, I mean I thought they taste a little citrusy but it turns out it’s my tastebuds that deceive me because they are in fact flavorless. Gave some to a friend - he absolutely loved them and now he wants me to include him in my order. But the best part is hydration tablets and how awesome that works. Aforementioned friend sweat...
