Preparation and directions
Empty one 82g sachet into 600ml water and shake until dissolved. Sip little and often during prolonged endurance exercise.
Training and event use

Training: Mix one sachet with 600ml water and sip during prolonged exercise. One sachet provides 80g carbohydrate, so build towards it in training and count every gel, chew, bar and drink in the same hourly total.

Event use: A compact way to carry 80g carbohydrate for long races. Rehearse the exact concentration, bottle size, fluid intake and any separate sodium plan before race day.

Certification and testing
Informed Sport certified and batch tested under the programme.
Cautions and individual suitability
This is a concentrated 80g carbohydrate serving. Build tolerance gradually and include all food and drink in your hourly total. The listed nutrition contains 0g salt, so add sodium separately where your practised sweat and hydration plan requires it.

High-carbohydrate drink mix

A substantial part of the plan in one 600ml bottle

Beta Fuel 80 is designed for endurance sessions lasting more than two hours. One sachet provides 80g carbohydrate, so it should be counted inside the whole hourly plan rather than added on top without adjustment.

Clear number

80g in one bottle

One sachet gives a visible carbohydrate contribution without counting several small items.

Formula

1:0.8 dual-source carbohydrate

Maltodextrin and fructose are combined in the ratio stated by SiS for high carbohydrate delivery.

Format

Fifteen measured sessions

The box format suits repeated long-session practice before an event.

How to use it

Mix accurately, then plan around it

SiS positions Beta Fuel 80 for exercise longer than two hours. The bottle is both fuel and fluid, but local conditions can change how much additional water or sodium the session needs.

01

Start with 600ml water

Add one full sachet to 600ml water and shake until dissolved.

02

Count the whole 80g

Place the bottle inside the session's total carbohydrate and fluid targets.

03

Practise the drinking rhythm

Decide when the bottle starts, how quickly it is consumed and what other fuel is still required.

Choose the format

Drink mix, gels and solid fuel solve different carrying jobs

Build the combination you can transport, tolerate and use accurately across the whole session.

Beta Fuel 80 questions

Know the bottle before it reaches race day

Clear numbers make the product easier to place inside a complete fuel plan.

How much carbohydrate is in one sachet?

One 82g sachet provides 80g carbohydrate. Count the full amount inside the whole session plan.

How much water should I use?

SiS directs one sachet to be mixed with 600ml water. Follow the current pack.

What type of session is Beta Fuel 80 for?

SiS positions it for endurance exercise lasting more than two hours. Shorter or easier sessions may need less carbohydrate.

What does the 1:0.8 ratio mean?

It is the stated ratio of maltodextrin to fructose in the carbohydrate blend. It does not remove the need to practise the intake.

Which flavours are available?

The current product is set up with Orange, Red Berry and Strawberry & Lime variants. Availability is shown on the page.

Should I try it for the first time on race day?

No. Test the flavour, concentration, drinking rhythm and full carbohydrate plan in training first.

Build the plan

Choose the fuel format around the session

Use drink mix where bottles fit, then add only the gels, chews or bars the remaining plan requires.

Check each product page for current price and availability.
