Fuel

  • 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...

  • Running Hat

Working with Precision Fuel & Hydration has ensured I perform at my very best by helping me understand how my body fuels, and they’ve helped me develop a fueling and hydration strategy that works for me.

Leon Chevalier

athlete country flag

Multiple IRONMAN Champion

Leon is a French professional long distance triathlete and a Master of Chemical Engineering student.

In his debut year as a pro athlete in 2021, Leon moved up from 420th to 22nd in the PTO world rankings, thanks notably to a win at IRONMAN Mallorca and a 3rd place finish in what was his first crack at the full distance at IRONMAN Bolton in the UK.

Leon was introduced to Precision Fuel & Hydration by friend and fellow triathlete Mark Threlfall, just as PF&H were embarking on their fueling journey. Leon is quite a salty sweater, so uses a winning combo of PH 1500 and PF 30 in training and races.

Working with Precision Fuel & Hydration has ensured I perform at my very best by helping me understand how my body fuels, and they’ve helped me develop a fueling and hydration strategy that works for me.
