No more Gut issues
Before using PH&F I’ve used different gel during my training and race day but after my race , I always issues with my gut But since I used the PH&F products I have no more issues
Great products that work for me!
Having tried numerous makes of gels with mixed results, this year I decided to try Precision Hydration’s products. At long last I have found products which don’t make me gag or give me heartburn. For me the gels score top marks on flavour/consistency and are easy to consume while running.
Ottima scoperta
Mi trovo molto bene con tutti i prodotti. Ci è voluto veramente poco per abituarsi e devo dire che in gara aiutano assai
IronMan Precision Debut
Precision helped power me to an absolutely awesome first IronMan at IronMan WA 2025. I had a sweat test prior to the event, Corey was great and I found my electrolytes weren't high enough in sodium to ensure I made it through the day feeling strong. Precision 1000 and 1500 electrolyte tablets were so easy to use, and I followed the tips provided via the Precision emails. Having Precision as the chosen electrolyte for the race was fantastic as I could just grab bidons at the aid stations and knew exactly what I was getting. I stuffed the Precision Mint and Lemon chew bars up my aero sleeves on the bike for easy to access additional carbs on the bike. It worked as I powered through the run to finish on the podium and felt great throughout the race. I also love the 90 & 300 flow packs to fill gel bottles, also less waste produced. I am having another crack at IronMan WA this year and hope to improve my time. Precision will be part of my training and race day.
