Who Precision Fuel & Hydration Is
Precision Fuel & Hydration (PF&H) was founded in 2011 in the UK by Andy Blow, a former sports scientist with the Benetton and Renault Formula 1 teams. The brand's hook was that sweat sodium concentration varies enormously between athletes, and that off-the-shelf one-size-fits-all electrolyte products often missed the mark. PF&H built a sweat-testing service alongside a tiered electrolyte product line.
The Range
The PH electrolyte line is named by sodium concentration per litre when mixed at the recommended dose - PH 250, PH 500, PH 1000, PH 1500 (the number is mg sodium per litre). Athletes who sweat saltily reach for the higher concentrations; lighter sweaters for the lower ones. The brand also sells PF Energy gels and PF Carb & Electrolyte drink mixes for in-session fuelling.
Formulation Notes
The tiered approach is the brand's signature. PH 250 sits in the daily-hydration band; PH 1500 sits in the heavy-sweat band that suits hot races or particularly salty sweaters. Sweat tests offered by the brand identify which tier an individual athlete should match to.
Who Reaches For Precision
Triathletes preparing for long-course events, marathoners, ultra runners, and adventure-race athletes - particularly those who've worked with sports scientists or coaches who recommend sweat-test-informed dosing. Available in Australia through endurance retailers and online.
Best Fit For
- Athletes who've had a sweat test or know their sweat-sodium profile
- Tiered sodium dosing matched to individual physiology
- Long-course triathlon and ultra-distance race day
Worth Considering Alongside
If you're weighing up Precision Fuel & Hydration against others in the same use-case bucket, these brand profiles cover the same ground from different angles:
- LMNT - High-sodium electrolyte sachet brand co-founded by Robb Wolf, distributed internationally.
- Sodii - Australian high-sodium electrolyte brand built around HASTA-certified sachets, available through Drink SALTD and direct.
- SiS - Science in Sport - UK endurance-focused sports nutrition brand with a strong cycling and triathlon presence in Australia.
- Tailwind Nutrition - Colorado-founded endurance powder that combines carbohydrate and electrolytes in one bottle - popular with ultra and trail runners.
Frequently Asked
What is a sweat test?
A lab sweat test measures the sodium concentration in an individual's sweat to inform electrolyte dosing during long events. Precision Fuel & Hydration is one of the established providers; the test typically involves placing a patch on the forearm during a sweat-inducing activity.
What do the PH numbers mean?
Precision's PH range is named by sodium concentration per litre when mixed at the recommended dose - PH 250 has 250 mg/L sodium, PH 1500 has 1500 mg/L. Athletes match the tier to their sweat-sodium profile (or use the lighter end if they haven't tested).
Where can I buy Precision Fuel & Hydration in Australia?
Available through Australian endurance specialty retailers and online direct from pfandh.com. The brand also operates the sweat-testing service separately from the product line.
