Precision Fuel & Hydration have helped me balance my hydration and electrolyte needs - it's been a game-changer.

Jocelyn McCauley

4x IRONMAN® Champion

Jocelyn focuses on racing 70.3®, 100km, and full-distance triathlons.

Originally from Texas, now based in Boise, Jocelyn is a multiple IRONMAN® champ most recently winning IRONMAN® Texas in 2022.

Jocelyn discovered Precision Fuel & Hydration at a PTO 100km race. She’s a moderate sodium sweater but has a high sweat rate, so preloads with PH 1500 before races and drinks PH 1000 during.

Away from the sport, Jocelyn is a wife and mother of two daughters, Emi (10) and Sydney (2). She loves to bake and cook in her spare time.

Precision Fuel & Hydration have helped me balance my hydration and electrolyte needs - it's been a game-changer.
