Nothing but positives
Been so impressed with precision. From the fuelling plan, to the delivery the website and customer service has been brilliant. As for the products I’ve found they sit really nicely on my stomach. As someone with coeliac disease this has been really reassuring and nice to find a product that feel safe with.

Best brand on the market
Really great customer service, I absolutely love the products and the support I got (as a first time marathon runner) was excellent. The hydration/fuelling calculator is unbelievably good

Best Fueling for Distance Runners
Outstanding products across the board - appreciate the flavor, digestibility and wide range of options. I use them for my long runs and have never felt better since I started using them. What really sets their team apart is the personalized responses I've received to questions about my fueling strategy for both long runs and races. They always respond very quickly and provide thorough, clear explanations.

Exercise = Hydration
Having been a distance runner for 50 years and only just recently discovering the absolute benefits and necessity of proper hydration, I now use Precision Hydration tablets every day. My ultra marathon son put me onto to them and they HAVE worked brilliantly.

10 out of 10 👏🏻
Fantastic experience using Precision Fuel & Hydration, the information that they share across all platforms has been royal to me and my fuelling plans. As someone that is relatively new to fuelling the information and guidance has been essential for me. Then they back all the information will a top product, I have tried countless gels in the past and nothing has performed for me like this product.

Naturally The Best
Best electrolyte tablets on the market. Easy on the stomach whilst training. Delicious light citrus flavour. Absolutely no itchy gums from unwanted sugar. Whether it's a pre training electrolyte load, mid session top up or a quiet sip during the night whilst sleeping. These are the only go to electrolyte tablets you'll ever need.

Excellent!
Excellent products, easy to digest and easy on the stomach. I am currently training for my 1st marathon and used the gels and chews during a recent 19 mile run and still had energy at the end to run further if I had needed to.
