Customer Testimonials

Matt Ralphs ( Pro triathlete):

Carbon Endurance has been my go to for the past year and a half and has played a pivotal role in my triathlon journey. Not only are the products they stock the best in the business but having the guidance of John and his input in order to best utilise them to get the most out of the products really does ensure that whether training or racing you will get the most out of yourself.

My favourite products include Precision Fuel and Hydration's drink mixes and Pillar Performance's range of micro nutrition.

Mari Marincowitz (Elite Ultra Trail runner)

As an ultra trail runner, finding a nutrition partner who truly gets it has been a game-changer—and that’s exactly what I’ve found with Carbon Endurance. They don’t just sell products; they provide knowledge, support, and a real understanding of what works for me as an individual.

What I love most is their educational approach. They take the time to explain the "why" behind every nutrition plan, helping me make informed decisions rather than just following a generic recipe. They understand that every athlete is different, and their focus on testing products, combinations, and finding the right solutions has made a huge difference in my performance and overall experience.

There’s also a personal touch to everything they do. Whether it’s advice, encouragement, or just checking in, they genuinely care about improving the lives of the athletes they work with. It’s not just about science (though they’ve got that covered, too)—it’s about connecting with people and helping them thrive.

I couldn’t recommend Carbon Endurance more. They’ve helped me fuel smarter, train better, and feel more confident every step of the way

Kelly Scates ( triathlete and AG podium regular):

“I don’t cramp. Why would I worry about electrolytes?”

In over 6 years as a triathlon enthusiast I had never - not once - considered my electrolyte intake. Electrolytes were something big men with cramping issues worried about. I knew in the recesses of my brain that my sports drink contained them and therefore I was probably taking in enough, right?

I was introduced to the concept of a sweat test by Carbon Endurance in 2019. This was a test to measure the sodium composition of sweat (not to be confused with sweat rate, which is the amount of sweat per hour and is condition dependent). The test itself was extremely elegant – two small electrodes are attached to the skin to stimulate the sweat impulse and that sweat is gathered and run through a machine to accurately calculate sodium loss. That simple.

The results were staggering. Turns out my sodium loss is high. Very high. Much higher than any sports drink could even begin to replenish. I had been training and racing for 6 years with an extremely depleted electrolyte balance. Somehow, I had dodged the cramping bullet but the effects of this depletion had been evident in every race and suddenly made sense. Every race I’d ever done felt like a gradual loss of tire pressure from wire to wire, a fight to hold onto energy. I had always assumed this was normal for long course triathlon. How wrong I was.

Immediately after the test, I received a comprehensive hydration strategy from Carbon Endurance, with products from Precision Hydration. The strategy was tailor made to my specific needs based on my sodium loss and sweat rate. It included plans for race preloading, as well as sodium intake during a race.

Shortly after the sweat test, I raced Ironman 70.3 Durban. I followed the sodium strategy and used PH products as prescribed. It was a race experience like none other. The biggest difference was in my energy levels throughout the race. For the first time, I didn’t feel as if the life had been kicked out of me in the last 5km of the run. I took 26 minutes off the previous year’s time and hit my first 5-hour 70.3, with a half marathon PB by far. I finished 6^th in my AG and 10^th AG overall. The difference to previous races was so stark I felt like I had discovered a silver bullet; I almost felt like I was cheating. This has continued in every race I have done since.

As athletes at any level, we are obsessed with the controllables. We put in the hard miles, spend thousands on carbon-plated shoes and the latest watt-saving tech and feverishly check the race weather forecast for weeks prior as if we can change it. For me, this is one more thing I can control, and there is nothing like going into a race with the confidence to know that my hydration strategy is sorted, no matter the conditions.
