WHAT ARE THE BEST ENERGY BARS FOR LONG RIDES?

When it comes to long rides, choosing the right energy bar can make or break your endurance. A good bar provides balanced carbs, proteins, and fats while being easy to digest on the move. In this guide, we explore what makes an energy bar effective, review top brands, and offer practical tips for maximizing performance and avoiding energy crashes. Whether you're a seasoned cyclist, a triathlete, or someone training for endurance events, this comprehensive review will help you fuel with confidence and consistency.

Nutrition fundamentals for long rides


Long-distance cycling requires a careful balance of macronutrients, hydration, and timing. Energy bars serve as compact sources of calories that support glycogen replenishment while minimizing digestive strain. Understanding what makes an energy bar suitable for endurance is key to maximizing performance.


Core components of an endurance bar


The best energy bars for long rides are not simply about taste. They are designed to deliver a calculated balance of carbohydrates, proteins, and fats that fuel both immediate energy needs and sustained endurance. Carbohydrates typically dominate, making up 60–70% of the bar's calorie profile, but protein and fats are critical for preventing muscle breakdown and extending satiety.


  • Carbohydrates: Essential for glycogen replacement and quick energy.

  • Protein: Helps with muscle recovery during and after the ride.

  • Healthy fats: Provide slow-burning fuel for longer rides.

  • Electrolytes: Support hydration and prevent cramping.


The glycemic index factor


Bars with high glycemic carbohydrates like glucose or maltodextrin deliver quick bursts of energy, which are ideal for immediate needs during intense climbs. Low glycemic sources like oats and brown rice syrup sustain energy over time. A combination of both is often optimal for rides exceeding two hours, ensuring both quick access and steady release of energy.


Ultimately, nutrition fundamentals highlight that choosing the right energy bar is not about one-size-fits-all solutions. Instead, it's about balancing macronutrients, digestibility, and timing according to your unique training demands.


Top energy bars for cyclists


Cyclists and endurance athletes have a wide range of energy bar options, each with unique nutritional profiles and formulations. The choice often depends on ride length, intensity, and personal digestion comfort. Below, we review some of the most widely trusted bars on the market.


Clif Bar: The reliable all-rounder


Clif Bars remain a staple among cyclists for their balance of complex carbohydrates, protein, and vitamins. With around 250 calories and 9 grams of protein, they provide sustained fuel that suits both moderate and long rides. Their softer texture also makes them easier to chew mid-ride, even under fatigue.


SIS Go Energy Bar: Fast absorption


Science in Sport (SIS) produces bars that prioritize rapid carbohydrate absorption. Containing around 30 grams of carbs per serving, SIS Go Bars are tailored for athletes who want easily digestible fuel without excessive fat or fiber, minimizing the risk of stomach issues on intense rides.


RXBAR: Clean ingredients


RXBARs highlight transparency, listing ingredients like dates, egg whites, and nuts on the packaging. These bars provide a protein-rich alternative that balances natural sugars with sustained energy. While slightly denser in texture, they appeal to athletes who value whole-food formulations.


  • Clif Bar: Balanced carbs and protein for steady energy.

  • SIS Go: Quick-digesting for high-intensity rides.

  • RXBAR: Clean label and protein-rich profile.

  • Kind Bar: Nut-based, good for steady release.


Choosing among these bars requires considering digestion comfort and ride intensity. A Clif Bar might be ideal for a 4-hour endurance session, while a SIS Go Bar could shine during a high-intensity interval workout. RXBARs, meanwhile, suit recovery or lower-intensity rides where natural ingredients are preferred.

Practical fueling strategies


Selecting the right energy bar is only part of the equation. Timing, frequency, and hydration strategies determine how effective your fueling will be during long rides. Proper planning prevents "bonking," the dreaded energy crash that occurs when glycogen reserves are depleted.


Timing your intake


Sports nutritionists often recommend consuming 30–60 grams of carbohydrates per hour during rides longer than 90 minutes. This equates to roughly one standard energy bar or half a high-carb bar every 45 minutes to one hour. Eating small portions consistently is more effective than waiting until fatigue sets in.


Pairing with hydration


Energy bars work best when paired with adequate hydration. Drinking water or an electrolyte solution alongside a bar ensures proper digestion and prevents gastrointestinal discomfort. Bars high in fiber or protein require additional fluids to avoid stomach heaviness during rides.


Customizing for personal tolerance


Every cyclist has different digestion tolerances. Some may thrive on nut-based bars, while others may struggle with their fat content. Testing different products during training, rather than on race day, is essential for identifying what works best. Adjustments based on temperature, terrain, and ride intensity also help optimize fueling strategies.


  • Consume 30–60g carbs per hour on long rides.

  • Hydrate consistently to support digestion.

  • Test bar types during training, not events.

  • Adjust fueling by ride intensity and weather.


Ultimately, practical fueling strategies emphasize consistency, hydration, and personalization. A rider who masters these fundamentals with the right energy bar selection will not only prevent fatigue but also sustain peak performance deep into a long ride.
