What's in the bottle

One scoop.
Three jobs. Eight hundred calories.

Nothing engineered to win the in-store taste test. Everything engineered to still go down on day three.

01
Real Fruit

Freeze-dried berries, banana, lemon juice. Actual cocoa. Micronutrients for real food performance.

5-10%by weight
02
Dual-source Carbs

Maltodextrin, fructose, good 'ole sugar — multi-source so the gut keeps absorbing past the point a single-sugar fuel would stall.

~160gper bottle
03
Plant Protein

Pea protein: vegan, balanced, hypoallergenic. Not enough to compete with carbs for absorption — exactly enough to keep the body from eating itself on day four.

Why this bottle

Dan bonked in Fiji.
We fixed it.

Eco Challenge Fiji · 2019 · Day 1

Day one - we went from first place to dead last in the space of a few hours. Dan went from being a paddling powerhouse to face-down in the mud. Dozens of teams passed us as we waited for him to recover. It wasn't fast, and it wasn't pretty, but we clawed our way back to being the top American team.

It shouldn't take that much grit and determination! Fuel right, race smart. We did our best to learn the lesson, and along the way we started making our own recipe of powdered fuel. Designed to put a rediculous amount of calories in one bike bottle, it's easier to manage than anything else we've found, and flavored to still be drinkable on day 8. Eventually, we started selling it.

“I needed something simple, so I can focus on everything else.”

The Lineup

Four flavors.
All quiet on purpose.

Each one dialed back — bright enough to want, faint enough to keep wanting. Horchata is the team favorite.

The reviews that count
come from race three.

After the first sip, anything tastes fine. We listen to the third or fourth race in a row — when the only loyalty left is to what still works.

“Hour 60. Salish Sea. Still going down.”
By the third day of WA360 most fuels in my pack were a liability. This was the one I kept reaching for. It got easier as the race got harder — the only review that matters.

“It will always go down, and STAY down.”
Between expedition races and endurance MTB, I keep a steady supply on hand. Sometimes I'm yearning for something savory, sometimes sweet — but this always goes down.

“Simplifies so much about my nutrition.”
Instead of thinking about how many gels, salt, and fluids I'm getting every hour, this simplifies it. One bottle, 2–4 hours, done.

And when 4HF isn't the job

Two more bottles.
For the corners 4HF wasn't built for.

4 Hour Fuel covers ninety percent of what our team races. These cover the other ten — short and red-hot, or long and off-effort.

No. 02
Redline Ultra
For maximum carb absorption

Sub-ten hours, threshold and above. 120g of carb per hour, dual-source, flavored with powdered lemon juice. We start races with this, and use it for maximum effort training.

No. 03
Smoothies & Mash
A taste of home — without nuking your gut

Real food that rehydrates in sixty seconds, even with cold water. Mashed potatoes and more - basically what we bring if we know we'll crave something with texture.

Shop Smoothies & Mash

Real fruit, real food

What's on the label is what's in the bottle. No flavor systems, no proprietary blends, no syllables your grandmother wouldn't recognize.

Tuned for the thousandth sip

Less sweet, less aroma, less of everything that flips the stomach at hour eight. Quiet calories that still go down when the loud ones can't.
