Fixx Nutrition Tryout Pack
Cramping at mile 10 isn't bad luck — it's bad preparation. You've probably felt a calf seize at the worst possible moment, popped a salt tab that didn't help, and finished the day swearing you'd find something that actually works. Here's what most athletes don't realize: cramp prevention has more to do with the nervous system than electrolytes, and most fueling brands don't address it at all.
This is the exact 7-pack The Feed built so you can test every Fixx Nutrition format: CrampFix shots, Gel X Pro caffeinated gels, Fuel X, and Fuel X PRO drink mixes — across real training before you commit to race day.
Cramp Relief That Actually Works
CrampFix uses a fast nervous-system reflex, not electrolyte replacement. The strong sour flavor activates sensory receptors in your mouth and throat that override the misfiring motor neurons causing your cramp, with relief typically arriving in 30 to 60 seconds.
Every Format, One Pack
CrampFix for cramp prevention and rescue, Fuel X and Fuel X PRO for hydration and endurance fueling, and Gel X Pro for late-session caffeine — all four product types in one box so you know what works before it costs you a finish.
Informed Sport Certified
Every CrampFix product is third-party batch-tested for banned substances under Informed Sport certification, the same standard required by Olympic and professional athletes. It's why the Wallabies, Springboks, and UK Cricket and Football teams use Fixx as their cramp protocol.
Fuel X, Fuel X PRO, and Gel X Pro all use a dual-source carbohydrate blend of glucose and fructose, absorbed through two separate intestinal pathways simultaneously. That means your muscles can access up to 90 grams of carbs per hour, roughly 50% more than single-sugar fuels — without overwhelming your gut at race pace. Fuel X PRO adds amino acids on top, making it the call for longer efforts and back-to-back training days.
Before your workout: Take a CrampFix shot 5–10 minutes out if you know a muscle tends to cramp, or carry one in your jersey for mid-effort rescue.
During your effort: Mix Fuel X or Fuel X PRO in your bottle for sessions longer than an hour. Take a Gel X Pro late in the effort when you need a caffeine push.
Pro tip: Test every format at different intensities across multiple sessions — so race day is never a first-time experiment.
Fixx Nutrition is one of the most-trusted endurance brands at The Feed, favored by triathletes, ultra-runners, and gravel cyclists who cite genuinely fast cramp relief, gut-friendly hydration, and clean flavors that don't fatigue over long sessions.
This isn't just another variety pack. This is seven products, four formats, one training block, so you show up on race day already knowing exactly what works.
Performance, Fixed.
What Is the Fixx Nutrition Tryout Pack?
The Fixx Nutrition Tryout Pack is The Feed's curated 7-product sampler containing two CrampFix shots, two caffeinated Gel X Pro gels, one Fuel X endurance drink mix, and two Fuel X PRO amino-acid drink mixes — built for endurance athletes who want to test the full range of Australian endurance brand Fixx Nutrition before committing to full boxes. Every product is built around real-world athletic validation: CrampFix is Informed Sport certified and used by the Wallabies, Springboks, and UK Cricket and Football teams, and the fueling line uses a dual-source glucose-fructose blend for higher carb absorption with less GI distress.
CrampFix is the product that put Fixx on our radar. We test everything we sell, and a product that can shut down a calf cramp in under a minute is the kind of innovation we don't ignore. Fixx Nutrition started in 2016 in Burleigh Heads, Queensland, when co-founder Jan Buchegger ran a pickle-juice cramp-relief experiment on professional rugby athletes. The resulting CrampFix formula is now trusted by national rugby programs around the world. This pack is the easiest way to find out which Fixx product belongs in your kit.
