Why Neversecond C30 Fuel Bar is the Best Energy Bar for Endurance Athletes

Built for Athletes—Not Snackers

When it comes to fueling for performance, not all bars are created equal. Many energy bars on the market are little more than glorified granola bars—loaded with fat, fiber, and proteins that slow digestion and cause stomach distress during training or competition. The Neversecond C30 Fuel Bar was created with a singular purpose: to deliver fast, efficient, and stomach-friendly energy to athletes in motion. This is not a lifestyle bar—it’s a chewable performance tool.

Bite-Sized. Not Oversized

Every C30 Fuel Bar delivers 30 grams of carbohydrate. Our modular fueling system—spanning gels, drink mixes, and bars—is designed around this number. It makes fueling predictable, measurable, and easy to practice in training. With the C30 Fuel Bar, you know exactly how much energy you’re taking in—no guessing, no arbitrary serving sizes.

Optimized Blend for Maximum Absorption

The C30 Fuel Bar is formulated with a 2:1 glucose-to-fructose ratio, the gold standard for carbohydrate delivery. Why does this matter? Glucose and fructose use different absorption pathways in the gut. By combining them in this ratio, athletes can take in more carbohydrate per hour with less risk of gastrointestinal distress. While many bars overload on one sugar source, the C30 Fuel Bar is designed to maximize uptake while protecting the stomach—a crucial advantage when performance is on the line.

Easier to Eat at High Intensity

When you’re pushing hard, the last thing you want is a dense, chewy bar that takes minutes to get down. The C30 Fuel Bar was created with a smooth, soft texture that is easy to chew and swallow—even at high intensity when your mouth is dry and breathing is heavy. It’s compact in size, easy to hold, and disappears quickly without a lot of chewing. This means you can fuel fast and get back to focusing on your effort, not on fighting your food.

Stomach-Friendly by Design

Unlike most bars, the C30 Fuel Bar is intentionally low in fat, fiber, and protein. While those nutrients are essential for recovery or everyday nutrition, they slow digestion and can wreak havoc on the gut during endurance efforts. By minimizing them, we’ve created a bar that absorbs quickly and reduces the risk of stomach upset, cramping, or bloating. Whether you’re running, riding, or racing, you can count on the C30 Fuel Bar to sit light in the stomach and deliver energy when you need it most.

Weather-Proof Performance

Athletes don’t stop for the weather, so neither should their fueling. The C30 Fuel Bar is engineered to perform in all conditions. It stays soft in cold weather—no more rock-hard bars on winter rides—and remains non-sticky in hot weather, so you won’t end up with a melted mess in your jersey pocket. Whether it’s a frosty mountain run or a sweltering summer ride, the C30 Bar is built to keep up.

Before, During, or Between Sessions

The compact size and easy digestibility of the C30 Fuel Bar make it versatile. It’s perfect for:

• Before training or racing: A quick pre-session top-up of 30g carbohydrate.

• During sessions: A steady fuel source that complements gels and drink mixes in your fueling plan.

• Between sessions: A light, fast-absorbing carbohydrate source to bridge recovery between workouts.

Not Another Lifestyle Bar

Walk down any grocery aisle and you’ll see hundreds of bars marketed as “healthy” snacks. But most of these products are designed for convenience and flavor, not performance. They’re packed with nuts, seeds, oats, chocolate, or protein powders—ingredients that are slow to digest and often disruptive to the gut during exercise. The C30 Fuel Bar is different. Every detail—from the carbohydrate ratio to the soft texture—was engineered for one purpose: to help athletes perform their best.

Fits Into the Neversecond System

One of the biggest advantages of the C30 Fuel Bar is how seamlessly it fits into the Neversecond System of Success. Alongside our C30 Energy Gels, C30+ Caffeine Gels, and C30/C90 Sports Drink Mixes, the bar delivers fueling in easy-to-track 30g carbohydrate units. This modular system allows athletes to build and practice fueling strategies tailored to their individual needs. For example, an athlete aiming for 90g of carbohydrate per hour can combine three different Neversecond products—say, a gel, a drink mix, and a bar—to hit the target without stress or confusion.

Trusted by Elite Athletes

From ultrarunners to long course triathletes, gravel racers to professional cyclists, elite athletes across disciplines trust Neversecond products to fuel their biggest efforts. The C30 Fuel Bar has become a favorite for its ease of use, reliable absorption, and predictable energy delivery. These are athletes for whom fueling mistakes can cost podiums. If they rely on it, you can too.

Designed for Real-World Training and Racing

Performance fueling doesn’t happen in a lab—it happens on the road, trail, or course. The C30 Fuel Bar was tested by athletes in real conditions: during long rides, grueling runs, and back-to-back training sessions. The feedback was consistent: athletes loved the compact size, the easy chew, and the stomach comfort. It became clear that this wasn’t just another product. It was a real solution to the challenges athletes face when fueling in motion.

Why Choose the C30 Fuel Bar Over Other Options?

• Precision Carbohydrate Content: Precise 30g carbohydrate per bar = no guessing.

• Optimized Blend: 2:1 glucose-to-fructose ratio for maximum uptake.

• Athlete-Focused Texture: Smooth, soft, and easy to consume at intensity.

• Gut-Friendly: Low in fat, fiber, and protein to reduce GI distress.

• All-Weather Durability: Stays soft in cold and non-sticky in heat.

• System Compatibility: Fits seamlessly into Neversecond’s modular fueling approach.

Other bars might taste good in the kitchen, but when you’re in motion, nothing matches the precision and practicality of the C30 Fuel Bar.

How to Use the C30 Fuel Bar

For best results, athletes should incorporate the bar into their training to practice fueling strategies. A general guideline:

• Consume one C30 Fuel Bar (30g carbohydrate) as a chewable alternative to energy gels during endurance efforts.

• Pair with C30 or C90 Drink Mixes to meet higher hourly carbohydrate needs.

• Use before training sessions to top off glycogen stores without weighing down the stomach.

Practicing with the bar ensures your gut adapts, giving you confidence to execute your fueling plan on race day.
