I raced Ironman Malaysia as a professional and fell apart at hour three — not from lack of fitness, but from sodium mismanagement in extreme heat. After coaching hundreds of athletes and watching the same pattern at every level of the sport, I built the system I wish had existed.
Professional racing experience — Ironman & long-course triathlon across extreme heat conditions
Coaching operation across Australia — 150+ endurance athletes — real-world field testing base
Formulated around exercise physiology — Peer-reviewed research, not marketing assumptions
Built in Perth, Western Australia — Where heat and training volume make hydration a constant variable
Hydration is a performance variable. It should be treated like one.
The sodium problem
Why hydration fails for many athletes
Most products assume every athlete loses sodium at the same rate. The science says otherwise. Sodium loss can vary up to 10× between individuals — fixed-dose drinks cannot account for that.
Traditional hydration
Sodium is locked into the drink. One formula, one dose — regardless of your sweat rate, the heat, or how long you're out.
- Sodium locked into every serve
- Fixed dose — no adjustment for heat or sweat rate
- Based on average assumptions, not individual physiology
- Adjusting sodium means adjusting total fluid volume
The Lytework system
Sodium is separated from fluid. You control the dose — based on conditions, session length, and your individual sweat rate.
- Sodium separated from fluid — dose each independently
- Adjust intake based on conditions, not guesswork
- Precise dosing for your sweat rate and session length
- Works alongside your existing fuel and fluid strategy
THE LYTEWORK SYSTEM
Hydration shouldn't lock sodium into your drink.
Lytework separates sodium from fluid so you can adjust intake based on conditions, session length, and your individual sweat rate.
- Sodium separated from fluid
- Dose based on conditions, not guesswork
- No flavour, sugar, or mixing
- Compatible with any fuel strategy
- Built for long sessions and racing

DOSE BASED ON
PRECISION SODIUM DOSING
One capsule. You control the dose.
Precision sodium dosing — without sugar, flavour, or mixing.
Most hydration products either underdose sodium or bundle it with sugar and flavour.
Lytework delivers a clean, repeatable sodium dose you can scale depending on heat, duration, and sweat rate.
Built for real training conditions — long sessions, heavy sweaters, and race-day execution.
Lytework removes sugar, sweeteners, flavourings, and fillers commonly added to hydration products.
Fewer variables. Less gut distress. No flavour fatigue.
If an ingredient doesn’t support hydration or performance, it doesn’t belong.
Flavoured drinks become harder to tolerate over long sessions.
Sweetness builds, taste fatigue sets in, and athletes underdrink or stop taking electrolytes.
The Lytework dosing protocol
How to use Lytework
Start simple: 1–2 capsules with water. Adjust for time, heat, and sweat rate.
Lytework is designed for consistent use across daily training — not just race day. Want specifics? Use our Sodium & Sweat Calculator.
What's inside — and what's not
The System Difference
Control. Independently.
Drinks bundle sodium with fluid, flavour, and sugar. Lytework separates sodium so you can dose precisely — across any session, any conditions.
| Criteria |
Lytework
|
Electrolyte drinks
|
|---|---|---|
| Sodium precision |
Dose adjusts to the athlete, session demands, heat load, and sweat rate.
|
Often fixed per serve, making it harder to personalise sodium intake.
|
| Fluid flexibility |
Separates sodium from fluid so hydration can be adjusted independently.
|
Sodium and fluid are bundled together, limiting flexibility.
|
| Flavour fatigue |
No flavour. Easy to use consistently during long sessions or repeated use.
|
Flavoured drinks can become difficult to tolerate over time.
|
| Sugar reliance |
Sodium delivery without relying on sugar or sweetness.
|
Often combined with sugar, flavourings, or unnecessary additives.
|
| Portability |
Compact capsules. Easy to carry, dose, and use anywhere.
|
Powders, sachets, and bottles can be bulkier or require mixing.
|
| Dosing control |
Intake can scale up or down easily as conditions change.
|
Adjusting sodium usually requires changing total drink volume.
|
| System simplicity |
Works alongside any fuelling or hydration strategy.
|
Often combine hydration, sodium, and fuel into one fixed formula.
|
| Use across contexts |
Useful in racing, training, heat exposure, travel, and daily hydration.
|
Typically designed around drink preparation during exercise.

Who it's for
Lytework is for...
-
Endurance athletes
Triathletes, runners, cyclists & Hyrox athletes who need performance hydration without sugar or flavour.
-
Heavy sweaters and heat trainers
Individuals exposed to heat stress through training, sauna use, or naturally elevated sweat sodium loss.
-
LONG-DURATION & HIGH-INTENSITY TRAINING
Athletes training or racing long enough that hydration strategy becomes a performance limiter — not just a comfort factor.
Tested in training, racing, and heat.
Every result below is from an athlete using Lytework in real conditions. No lab settings, no incentivised reviews. Protocol data included.
I stopped cramping mid-race for the first time. The ability to dose based on conditions rather than a fixed serve size changed everything.
No flavour fatigue is a real thing. After 3 hours of training I could still take these without any issue — something I couldn't do with electrolyte drinks.
Simple product. I carry a few capsules and adjust based on how hot the day is. It fits into my existing setup without changing anything else.
Took my salt tabs during the ride and felt way better almost immediately. Simple change but it made a big difference.
Field testing is ongoing. Every athlete uses a personalised protocol calculated from their sweat rate, session length, and conditions. Join the waitlist to be part of the first drop.

A simple way to think about hydration
SALT is a decision framework — not a prescription. It helps you decide what to adjust when conditions change, without forcing changes to everything else.
Sodium
What varies most between athletes and sessions.
- Sodium loss can increase independently of carbs and fluid — especially in heat and longer sessions.
- Heavy sweaters can lose multiple grams of sodium per hour.
Amount (fluid)
What varies most between athletes and sessions.
- Fluid needs fluctuate moment to moment with temperature and intensity.
- Overdrinking can be as problematic as underdrinking for some athletes.
Load (carbs)
What varies most between athletes and sessions.
- Carb needs are driven by intensity, duration, and gut tolerance — not sodium loss.
- Keep carbs steady; adjust sodium when conditions change.
Timing (tolerance)
What varies most between athletes and sessions.
- Start earlier in heat and longer sessions to maintain performance and comfort.
- Spread intake to improve absorption and reduce GI stress.
Note: SALT explains principles. Individual needs vary by sweat rate, environment, intensity, and tolerance.
Sodium is the variable most athletes get wrong. Lytework is built to fix that — nothing else, nothing extra.
If sodium has cost you a race or a session, this is what you should have had.
Lytework delivers sodium only — nothing unnecessary — so you can hydrate with precision, not guesswork.
- High sodium
- No flavour, no sugar, no fillers
- Easy to dose on the move
- Works with any hydration setup
- Gentle on the gut
- Built for endurance athletes
Frequently Asked Questions
Most athletes start with 1 capsule per hour and adjust based on heat, sweat rate, and session length. Our calculator gives a personalised range.
Yes. Lytework is sodium-first and designed to work alongside gels, carb drinks, or plain water.
No. Lytework contains no sugar, flavour, or sweeteners to avoid flavour fatigue and gut issues.
Lytework is formulated for regular use by endurance athletes. Always take capsules with water and adjust intake based on conditions.
Why endurance athletes are switching to electrolyte capsules
Most hydration products lock sodium into a fixed-ratio drink. For triathletes, Ironman athletes, ultra runners, and cyclists, that approach fails when heat rises or sessions extend. Lytework separates sodium from fluid — so you can dose precisely, based on your physiology.
How much sodium do athletes actually need?
Sweat sodium varies up to 10× between individuals. A fixed drink cannot account for that. Lytework lets you dose to your own sweat profile.
Electrolyte capsules vs electrolyte drinks
Capsules separate sodium from fluid, sugar, and flavour. Independent control. No flavour fatigue. Works alongside any hydration setup.
Ironman hydration strategy — why sodium is the variable
Most late-race performance losses in long-course triathlon trace back to sodium depletion, not carbohydrate. Manage it precisely with Lytework.
No sugar electrolytes for heat training
Sweetened drinks become unmanageable in sustained heat. Lytework has no sugar, no flavouring, no fillers — just a clean, scalable sodium dose.
