Best fueling and hydration products by a mile
Just completed my third Unbound Gravel 200 in record time. Switching to Precision Hydration and Fueling was a game changer for me. I’ve tried almost everything and these are the most customizable and effective products I’ve ever used. Easy on the stomach. Palatable. Effective. I love these products!

Great support and products
I met Precision at the SealSkinz running club and spoke to the guys about an upcoming event. I heard about the ‘fuelling plan’ on their website and gave that a go. As a novice the support was invaluable, as was the ease of the purchase. Answer a few questions and their recommendations can easily be added to your basket. It’s pain free! They remain easy to contact for advice and further support and they’ve secured a customer for life!

My new partner in sports nutrition!
I learned about Precision Fuel and Hydration through an event that I was participating in. I liked their approach of using science to fuel and hydrate the body properly. I’ve read many of their articles, and I’ve been trying a lot of their products. I did a free video consultation and I got my sweat test tested for sodium concentration. I love that their products are designed to complement the science of performance nutrition. I now have a plan to fuel and hydrate properly for my unique needs ...

I’ve found my gel brand…
Best gels I’ve tasted, don’t make me gag like some big name brands! My order arrived really quickly. I won’t use any other company now.

Gel 90g packed in resealable bag is great, both from functionality point of view but of course more importantly from my GI point of view :)
