Easy on the gut.
Easy to read.
Easy to like.
Testing your fuel only works if the fuel itself is kind to your stomach. Ours is built for exactly that.
Every gel, bar and drink mix uses a dual-source carbohydrate blend of glucose and fructose. That balance lets your body take on more carbohydrate per hour while reducing the GI distress that single-source fuel can cause. It is engineered to be kind to your gut at race intensity, not just on the sofa.
So when you rehearse your fuelling plan off this kit, you are training with formulas designed to sit easy when the effort is hardest.
Full ingredient and allergen information is listed on every product page, so you can check exactly what is in each format before you train with it.

Most people start with a single kit. If you would rather rehearse a whole race build in one go, you can take 2 or 3 in your one welcome order and the per-kit price drops. Entirely optional, the single kit above is all you need to get going.
Whether you take 1, 2 or 3, it counts as your one welcome order per new customer. This is a genuine sampling programme, so you can find what works before committing to full packs.

The science
Built on dual-carb science.
Dual-source carbohydrate for higher carb intake without the GI hit, paired with high-sodium electrolytes. The same formulas the kit lets you rehearse with.
50gCarbs per GEL50 & BAR50
90g/hrTrainable carb intake
1000mgSodium per SLT+ serve
100%Vegan & non-GMO
Designed and made in the UK. Dual-source carbohydrate across the range so you can push carb intake higher than single-source fuel allows.
Questions, without the fluff.
Everything you need to know before you try every flavour and format for £69.99.
What if I don't like one of the flavours?
That is exactly the point of the kit. You try every flavour and format across training, keep what works for you and skip the rest, all before you commit to a full pack. And if the kit as a whole is not for you, our 30-day money-back guarantee has you covered.
Is this a subscription?
No. The Welcome Kit is a one-off purchase. No auto-charge, no hidden trial. If you love it, you can move to Subscribe & Save at 15% off afterwards, entirely on your terms.
How fast does it ship?
Free UK delivery on every Welcome Kit, with tracking. EU delivery is available in 2 to 4 working days. You will get a dispatch email the moment it leaves us.
Can I reorder my favourites afterwards?
Yes. Once you know what your gut handles, you can buy any product as a full pack on the store, or set up Subscribe & Save at 15% off so your fuel arrives on a schedule that matches your training.
Why one order per new customer?
The Welcome Kit is a genuine first-order sampler for new customers, priced well below the value inside. Limiting it to one order per new customer keeps it that way. If you want to train through a longer block, you can take 2 or 3 kits in that one welcome order using the multi-buy options above.
Is STYRKR fuel easy on the gut?
Every gel, bar and drink mix uses a dual-source carbohydrate blend of glucose and fructose. That balance lets your body take on more carbohydrate per hour while reducing the GI distress that single-source fuel can cause. The kit is built so you can find what your gut handles in training, long before race day.
What if I don't love it?
You are covered by a 30-day money-back guarantee. Email hello@styrkr.com and we will refund the kit in full, no quibbles.
Still have a question? Email hello@styrkr.com and a real human will get back to you.
