complicated.
Ours isn't.
Stupid distances. Simple fuel.
Honey, tapioca syrup, and sea salt — combined at the ratio that research says matters for absorption. Real food, easy to carry.
Honey
Provides both fructose and glucose — with fructose as the dominant sugar. That's what makes it the backbone of the ratio.
provides both sugars
Tapioca Syrup
Glucose source. Fast-acting, easy on the gut. Pairs with honey at the ratio that matters.
provides the glucose
Sea Salt
Sodium. Helps your body actually absorb the energy. Also keeps you from cramping at hour six. Straightforward.

Everyone says 0.8:1. We did the math on what actually reaches your gut.
Wait, isn't it 0.8:1?

The dual-transporter ratio isn't our idea. It's been tested in labs and on course for over a decade. Here's where to start reading.
Fructose-Glucose Co-Ingestion
Multiple transporters (SGLT1 + GLUT5) absorb more carbohydrate per hour than glucose alone. More energy absorbed per hour than glucose alone — over 1g of carbs per minute with the right ratio.

Honey performs comparably to conventional glucose gels in controlled tests. Similar energy delivery, comparable gut tolerance.
→ Read ResearchSodium-Glucose Cotransport
Sodium drives glucose across the intestinal wall via SGLT1. It's not just about cramping — it's the mechanism that makes carb absorption work.

Simple fuel for stupid distances.
That's it.
