Endurance fuel
shouldn't be
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.

01 The Whole List
Ingredient 01

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

Ingredient 02

Tapioca Syrup

Glucose source. Fast-acting, easy on the gut. Pairs with honey at the ratio that matters.

provides the glucose

Ingredient 03

Sea Salt

Sodium. Helps your body actually absorb the energy. Also keeps you from cramping at hour six. Straightforward.

0.73:1 Fructose:Glucose

Everyone says 0.8:1. We did the math on what actually reaches your gut.

Wait, isn't it 0.8:1?

03 The Research

Don't take our word for it.

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 vs. Conventional Gels

Honey performs comparably to conventional glucose gels in controlled tests. Similar energy delivery, comparable gut tolerance.

Sodium-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.

Endurance sports shouldn't require a chemistry degree or a trust fund.

Simple fuel for stupid distances.

That's it.
