Trail Running

Depending on the distance of your trail run, we recommend bringing a few QuickFix Shots and/or 50mL Multi-Serve Bottles in your pack.


Drink 1 x 20ml QuickFix SHOT or 10-20ml about 5 minutes before when you normally cramp or when you start to feel your muscles tighten. If you are running long distance, drink one shot every 40-60 minutes to prevent cramps from returning.


Drink 15-20ml of CrampFix® at the first signs of cramping for rapid relief within 30 seconds to 2 minutes.


Drink 10ml of CrampFix® after running to prevent post-exercise cramps and to reduce muscle tightness. If you struggle with night cramps after a run, keep a bottle beside your bed or try our Rapid Mouth Spray.

“I usually do 4 to 5 ultra trail races every year. The distances are usually between 50km to 165km. Every time I do these runs I always take a CrampFix at the first sign of cramping up and it keeps the cramp away.” – Mark Beattie

Our Formula

CrampFix®’s proprietary formula has been created to contain just the right blend of astringency, pH and mineral content to provide rapid relief. Unlike some cramp management products, CrampFix® is a no-mix, liquid formula that provides an almost immediate effect to get rid of cramps that most commonly appear during endurance activities.

Our formula was specially developed to help high performing athletes to achieve their performance goals. Other cramp relief products on the market such as magnesium supplements, quinine and sodium may assist in preventing cramps; however, these are useless at the time of cramping due to the required time to digest and provide relief. CrampFix® works within 1-2 minutes to alleviate cramps.

CrampFix® is a concentrated proprietary blend so only small doses are required to get rid of muscle cramps. Our sports range has three flavours available; Lemon, Raspberry, & Espresso. All products are 100% natural, gluten-free, & vegan, and are made in Australia to HACCP quality standards. This highly effective formula is Informed Sport accredited, meaning every batch is tested for banned substances for athletes’ assurance.

How It Works

CrampFix® treats muscle cramps through the neuro-muscular system. Instead of treating the cramping muscle itself as most commonly done, CrampFix® treats the overactive nerves that are causing the muscles to cramp.

Drinking 10-20mL of CrampFix® stimulates the sensory nerves in the mouth and throat. A signal is then sent through the spinal cord to inhibit the overactive nerve signals. The overactive nerve signals going from the nerves to the cramping muscle are interrupted and the cramp is rapidly relieved or prevented.


It does what it says. I was put onto it by a mate doing triathlons and it’s saved me from cramping up at the UTA and a couple of other events. There’s no way I’d do an event without it.

I bought some CrampFix at the expo before UTA50. Used the single shots in the last 5k of my race when I felt a cramp coming on. It was like magic and helped stop the cramps from hitting. The salty taste was welcome after a few gels and sweet drinks.

“I recently purchased a box of CrampFix online as I consider myself to be one of the best crampers in the world. I’m currently training for the Brisbane Ultra and have never got through a training run without multiple cramps and I’ve tried absolutely everything to fix this problem with no solution and ended just running through them which used to sap my energy and ruin my confidence of finishing long runs. I’ve now headed out twice on Mt Cootha since your product arrived and pushed as hard as I could to bring on a cramp but didn’t get even the slightest flutter in the muscles. This stuff is truly amazing and I’ll refuse to run without it from now on!
Awesome work guys, much appreciated”
