  • Gels

    So tasty, they’re loved by folk who usually hate gels!

  • Drink Mix

    Master of all trades, jack of none

  • Chews

    So good, you’ll be lucky if you have any left for race day

Hydration

  • Tablets

    These tablets are where it all began for PF&H. Over a decade later, they're still topping the charts.

  • Packets

    Single-serving drink mixes so you can take just enough that you don't have to share!

  • Electrolyte Capsules

    Designed to be swallowed, not anything more embarrassing (people have asked! 😬)

Merch

  • Bottles

    Every time we see someone mixing up PH in a G@t*rade bottle, we die a little inside

  • Soft Flask

    The hip flask's less-cool-but-definitely-fitter cousin...

Stuart Hayes

Team GB Olympian

Stuart is a man of many talents. He's a world-class triathlete, coach, Team GB Olympian and WTS World Cup winner.

He won his first ITU World Triathlon series event title in Kitzbühel, Austria, in 2010 as he won a thrilling event in a time of one hour, 52 minutes and 32 seconds.

Stuart was then selected to represent Great Britain at the 2012 Summer Olympics in London alongside Alistair and Jonathan Brownlee. Stuart finished in 37th place but his main job in the race was to help the two Brownlee brothers, which he did to great success as Alistair finished in gold medal position and Jonny took bronze.

He continues to train and coach as part of Team Dillon Coaching, and Precision Fuel & Hydration remains an integral part of his hydration strategy.

Stu is also a magician...
