HYDRAX CORE
CORE is the during-session drink we actually use: dual-source carbs and a high-sodium electrolyte profile in one mix. Built for prolonged work, 70.3 bike, marathon miles, long rides, when you want fuel and fluid without juggling six gels and a separate salt plan.

What a real serve costs
Most drink mixes quote a cheap price per serve by shrinking the serve. Compare like for like: carbohydrate and sodium actually delivered per serve, then the cost to reach 85g of carbohydrate.
| What to check | HYDRAX CORE | Typical 40g drink mix | 3 gels + 1 electrolyte tab |
|---|---|---|---|
| Carbohydrate per serve | 85 g | 40 g | 75 g |
| Sodium per serve | 980 mg | 300–500 mg | ~500 mg |
| Cost per serve | $4.16 | ~$3.20 | ~$10.50 |
| Serves to reach 85 g carbs | 1 | 2.1 | 3.4 gels |
| Cost to reach 85 g carbs | $4.16 | ~$6.72 | ~$11.90 |
| Items to carry per hour | One bottle | Two scoops of mix | 3 gels + tab + water |
Comparison figures reflect common formats on the Australian market at the time of writing. Prices and formulations change, so run the maths yourself: divide the pack price by the number of serves, then check how much carbohydrate and sodium each serve actually contains.

High-carbohydrate hydration fuel designed to deliver energy and electrolytes efficiently during prolonged training and racing.
About HYDRAX CORE
HYDRAX CORE is a high-carbohydrate endurance hydration fuel designed for long training sessions and race-day execution.
Delivered in a 1.08 kg pouch (12 servings), CORE is built around a dual-carbohydrate system using a 2:1 ratio of maltodextrin and fructose, allowing athletes to structure carbohydrate intake deliberately across prolonged endurance efforts.
Each serving provides a high-sodium electrolyte profile, including 980 mg of sodium, alongside potassium and magnesium, reflecting the demands of long-duration training and racing where fluid and electrolyte planning becomes critical.
Rather than separating energy and hydration into multiple products, CORE is designed as a single, integrated fueling system, simplifying endurance nutrition planning across disciplines such as running, cycling, swimming, and triathlon — from short-course racing through to long-distance events.
Developed with precision and restraint, HYDRAX CORE focuses on composition, consistency, and control, without unnecessary additives or distractions.
Pair HYDRAX CORE with PRIMER for total endurance optimization.
Who HYDRAX CORE is for
HYDRAX CORE is built for endurance athletes who fuel deliberately.
It is used across endurance disciplines including running, cycling, swimming, and triathlon — from short-course events through to long-distance preparation such as marathon training, 70.3, and full-distance triathlon.
CORE is designed for athletes who plan carbohydrate and electrolyte intake over hours, not minutes.
Why a single integrated system
Long endurance sessions demand structured carbohydrate and electrolyte intake over prolonged periods.
Rather than separating energy and hydration into multiple products, HYDRAX CORE is designed as a single, integrated fueling system. This allows athletes to scale intake per bottle, per hour, and per session without juggling gels, salts, and drink mixes.
Directions for Use
Mix approximately 2 scoops (90 g) with 600 ml – 750 ml of water.
Consume during prolonged endurance exercise.
