National 24hr TT with PH hydration and fuel
In short; totally recommend PH for hydration and fuelling. In full; Heard about PH on a Trainer Road podcast and checked out the sweat test as I am a heavy sweater and suffered on long events. Delayed my first purchase but brought some hydration products in recent months in preparation for the national 24 hour time trial. Used them in training and high temps and was impressed with how they worked. Also helping with my recovery. PH gels were also released recently and I have had limited experience with sports nutrition in the past opting for ‘real food’. The clear 30 grams of carbs was really helpful as I have adopted a more structured approach to my fuelling for the first time. I have managed long events better and recovered quicker when fuelling properly. The National 24hr TT had exceptionally hot conditions and I ensured I preloaded the day before and prior to the event with pH1500. I changed my plan to use PH1000 and switched to PH1500 initially due to the excessive heat. There were high drop rates in the high temps and I managed where I have failed in the past. ‘You sweat a lot’ said a blunt passing rider, but I had it covered. I got behind in my drinking overnight and took on some blister pack tablets to compensate and got back on top of my fluid intake after that. Used the PH gels every hour of the 24 along with some solid carbs and took on a consistent 60grams. No GI issues experienced. They are sweet but neutral in flavour, I have completely avoided gels previously due to the weird synthetic flavours not appealing. Im sold on PH gels for a consistent palatable carb source. The products did the job and contributed to me hitting my target and completing my ‘BHAG’. Who knew a well thought out hydration and fuelling strategy would be so effective? Thanks PH. Totally recommended.

Perfect hydration
I have recently started using precision hydration products as I was struggling to hydrate correctly especially in the heat, after using the products I am extremely happy. After a 27 mile run in 29 degrees temp I would normally feel terrible and would have probably cut the run short, using precision hydration eliminated the feeling badly after the run and was able to complete my run without any bad feelings afterwards. Highly recommend this product if you sweat heavily.

Great products
I have started using the 1500 strength electrolyte drink followed advice from a pro triathlete friend, and having shocked myself with the sweat test result. I participate in open water endurance swimming events, primarily 5 - 10k distance. This culminated in a 10k (turned out to be 11.7k!) swim yesterday in the Lake District in hot weather. I took a sachet the afternoon before and one on the morning of the event (along with a PH gel) and for the first time, no debilitating cramp when you stop swimming to take on water during the event. I've tried other hydration products and, frankly, they didn't work but simply, this does. I used the drink in combination with the gels which also helped me to keep consistent times per 100m/500m throughout the swim. Thoroughly recommended, thank you.

First time returning customer review. Tennis player
Great company with lots of tips and advice to help an athlete/amateur perform their best. The online sweat test was very useful. I learned about Precision Hydration from a tennis podcast. Having never tried salt supplements before I did the online sweat test and bought the introductory pack. After trying the products according to my hydration strategy, I was absolutely staggered at how the salt products stopped me from feeling fatigued after a match and the following day like I used to feel without salt. Fantastic purchase. Personally I prefer the sachets as they are a pleasant flavour and easy to drink/digest. I found the tablets are a bit fizzy for my liking and not so comfortable to digest.

Excellent products
Excellent service and superb products, which really work for me as an endurance swimmer

Just the Job for keeping properly hydrated
Great stuff. I’m a ‘heavy sweater’ prone to cramping and living in a hot climate and PH1500 does the job really well.

The sweat test was great and helped me understand how to fuel long training sessions
Finally got the balance right

Game changer!
I discovered PH when looking for a solution to hydration having struggled at a few races due to poor hydration and eventual collapse when the products I had been using didn't provide what I needed. The products are brilliant and do what I expected and more. Since using them I have had improved performance due to being correctly hydrated with the required salts and I have also found my fatigue is delayed and recovery increased. The products being used in conjunction with a specific hydration plan (provided for free) has been an absolute game changer for Ultra races and training.

Couldn't recommend PH highly enough!
I opted to try Precision Hydration after doing a sweat test and hearing lots of good things with other runners. I tried their strategy on a couple of training runs and felt great. The first real test was on a Bob Graham round support, running 31 miles over Lake District fells and Mountains. I followed the recommended strategy to a tee and felt fantastic (relatively) throughout. Tasty and easy to consume. Can't recommend PH highly enough.

No more cramp!!
Superb products!! Having always struggled with cramp during high intensity indoor training and racing i turned to PH and I haven't looked back! No longer suffer from cramps and PH gives me the confidence to push hard without the worry of cramping. The new 30g gels taste amazing and provide an instant kick!! Looking forward to trying out the new drink mix this weekend.
