Maple Syrup Is Elite Endurance Fuel. But We Made It Better.

Here's why your great-grandmother's pantry staple outperforms most gels on the market — and how 2THRV took it even further.

Maple syrup has been sitting on breakfast tables for centuries.

Turns out it's also been quietly outperforming the lab-made fuel the sports nutrition industry charges a premium for.

This isn't a health food opinion. It's science. And once you understand why maple syrup works the way it does, you'll understand exactly why we chose it as the foundation of 2THRV — and why we didn't stop there.

Why Maple Syrup Actually Works

Your muscles run on carbohydrates during exercise. Specifically, they need glucose delivered consistently to keep you moving hard. The faster that glucose gets to your bloodstream without wrecking your gut, the better you perform.

Maple syrup is made up of sucrose — which is one molecule of glucose and one molecule of fructose bonded together. The moment it hits your digestive system, it splits and both molecules absorb fast, cleanly, and without the inflammation response that synthetic alternatives like maltodextrin are known to trigger.

A University of Montreal clinical trial — one of the first of its kind — found that maple syrup provides a pure, clean energy source for endurance athletes and can also help fight inflammation during exercise. Fleet Feet The study used 76 competitive cyclists over two hours of effort followed by a 20km time trial. Maple performed on par with commercial sports drinks for energy delivery — with zero artificial additives.

A separate groundbreaking study supported by Maple From Canada found that replacing refined sugar with pure maple syrup delivers measurable benefits for athletes' metabolism and performance — fuelling the body with a natural balance of carbohydrates, minerals, and antioxidants that keep energy levels steady throughout endurance efforts.

And unlike the synthetic powders in most gels, maple syrup comes loaded with over 67 polyphenols — natural antioxidants that fight the oxidative stress building up in your muscles while you run. Just a quarter cup of pure maple syrup provides over 100% of your daily value of manganese — a mineral that plays a direct role in converting carbohydrates into energy, meaning it actively helps your body get fuelled faster.

This is food that works with your physiology. Not against it.

The Problem With Maple Syrup on Its Own

Here's where we get honest.

Maple syrup is elite fuel. But it has one limitation that matters a lot for endurance athletes going longer than 90 minutes.

It's primarily glucose-dominant. That means it uses one absorption pathway — the SGLT1 transporter in your intestine. That transporter maxes out at around 60 grams of carbohydrate per hour. Once it's saturated, your body can't absorb any more glucose no matter how much you take in. The excess sits in your gut, causes discomfort, and leaves you under-fuelled in the back half of a long race.

Straight maple syrup is brilliant. But for a two, three, or four-hour effort? You need more than one lane open.

How 2THRV Solved It

This is where the formulation gets interesting.

Research published in PMC confirms that fructose absorption uses a completely different intestinal transporter — GLUT5 — which operates independently from the glucose pathway. Combining glucose and fructose intake takes advantage of both transport mechanisms simultaneously, meaningfully increasing the total amount of carbohydrate your body can absorb and use during exercise.

In other words: two transporters, two lanes, more fuel getting through to your muscles per hour.

The first study to test this combination found that when glucose and fructose were ingested together, carbohydrate oxidation rates were 50% higher compared to glucose alone. Sportsnutritionexperts That is a significant performance number. 50% more of what you eat actually reaching your muscles.

We add organic dates to 2THRV specifically for this reason.

Dates are naturally rich in fructose. When combined with the glucose and sucrose in maple syrup, they open up that second absorption lane. The result is a gel that delivers sustained energy across the full duration of your effort — not just the first hour.

Research shows that ingesting glucose and fructose together improved time trial performance by 8% compared to glucose alone, and 18% compared to water. Precision Fuel & Hydration These aren't marginal gains. For an athlete chasing a marathon PB or pushing through the final 20km of a century ride, that's the difference between a great race and a great day.

Then We Went Further

Dates don't just provide fructose. They also bring potassium, B vitamins, and fibre — nutrients that support sustained energy and muscle function over long efforts.

We add organic berries for polyphenols — compounds that actively reduce the oxidative stress accumulating in your muscles as the kilometres stack up.

Organic lemon juice buffers acidity and helps the whole formula absorb more efficiently.

Mineral salt replaces sodium lost through sweat, keeping your fluid balance and muscle firing on point.

Every ingredient in 2THRV earns its place. Nothing is there for texture, shelf life, or to make a label look impressive.

The Bottom Line

Maple syrup is one of the most underrated performance fuels on earth. The science backs it. Elite athletes have known it for years.

But we didn't just put maple syrup in a pouch and call it done.

We studied the research on dual-transporter carbohydrate absorption, identified the gap in a maple-only formula, and built around it with whole food ingredients that solve the problem naturally.

The result is a gel that gives you immediate energy from maple, sustained energy from dates, antioxidant support from berries, and electrolyte replenishment from mineral salt.

Whole food. Built for performance. Nothing your body doesn't recognise.

That's 2THRV.
