Cycling Energy Gels

Possibly the most convenient and effective way to fuel your body on the bike is with energy gels. Whether you're riding a 50k, century, or beyond, understanding how energy gels work with your body, and knowing when and how to use them for maximum performance benefits is key.

WHY USE AN ENERGY GEL FOR CYCLING?

Your body uses two sources of fuel to feed your muscles; fat and carbohydrates. While fat is widely available, it's slower to break down into usable energy, making it more ineffective when competing in an endurance cycling event over 2-3 hours.

This means your body will rely on carbohydrates as its primary fuel source. But your body can only store a limited amount of carbohydrates in the muscles, known as glycogen.

For example, when you are performing at a brisk pace this equates to approx. 90 minutes of effort, for a steady endurance pace you are looking at about 120 minutes (2 hours) of effort. These are the key facts to understand when and why you need to start fueling.

SO, HOW CAN AN ENERGY GEL HELP CYCLISTS?

In its simplest form, energy gels provide simple sugars that are first absorbed into your bloodstream as glucose giving you a spike in energy. It is then absorbed by active muscles and organs.

Each gel provides between 15 minutes to 45 minutes of energy with approximately 25g carbohydrates, in the form of simple sugars, an accessible energy source for your body to process.

However, it's not all about the carbohydrates, depending on the energy gel, other ingredients have been induced to to help boost your performance:

CAFFEINE - Can Improve Alertness & Concentration, Reaction Times and the ability to push harder for longer by lowering the perception of effort.

SODIUM (ELECTROLYTES) - Lack of sodium can cause - Muscle cramping, Heat illness, Inability to properly rehydrate, Increased risk for hyponatremia.

AMINO ACIDS (BCAAs) - Amino acids are the building blocks of muscle - Low levels of branched chain amino acids (BCAAs) may contribute to fatigue or the perception of fatigue through a process called 'central fatigue'.

Note: As caffeine is a stimulant consider alternating between caffeine and non-caffeine gels to ensure you don't take on too much.

WHEN SHOULD CYCLISTS TAKE AN ENERGY GEL?

Getting your fueling right is key, don't wait until you need fuel as this is too late. This is the main reason why people say they are bonking or hitting the wall. The ideal time to consume an energy gel depends on you and your body.

The normal calculation is that you will feel the effects of an energy gel roughly 15 minutes after consumption.

Doubling the intake is not the answer, taking two at a time doesn't mean you'll get twice the energy burst, instead you're likely to crash as your body attempts to process the sugar.

As an example for cyclists on long rides, this is a useful guide as to when you should take an energy gel using a 45 minute consumption gel:

50 MILE/80K RIDE (3 gels)

• Start (up to 15 mins before ride start)
• Miles 15 & 30

100 MILE/160K RIDE (5 gels + spare)

• Start (up to 15 mins before ride start)
• Mile 20, 40, 60, 80
• Have a spare for mile 90+

You will be looking to take on fuel via gels approximately every 45-60 minutes (15-20 miles) between gels, ensuring not to overload your stomach with the intake of too much simple sugar at once.

WARNING - Guides based on gels to be taken every 45 minutes.

Always check the packaging on energy gels for consumption information.

Some brands of energy gels recommend a gel every every 15 - 20 minutes (3 per hour), whilst others are designed to be taken every 45 minutes. Now think about that; would you really want to take on 12+ energy gels over the course of a 100 mile ride? Or would taking 6 of a different brand work better?  The big issue here is when someone under fuels - 1 energy gel doesn't always equal 1 energy gel.

ARE THEY GLOOPY? WHAT ARE GELS LIKE?

This is a very common question, and everyone has different tastes to what they like. Although usually water-based gels vary in consistency from chewy and thick to a drink-like consistency and with varied strength in taste.

With so many flavors on the market from citrus fruits, to the most decadent in desert flavors or your favorite espresso. The only way you will really know is to test a few different brands to see what consistency and flavor is for you.

SHOULD I TEST DIFFERENT GELS?

Practice, Practice, Practice. With all nutrition, you want to make sure you have a tried and tested method to get your required fueling on-board long before race day and this is no different with energy gels.

Throughout your training you will be upping the miles and the best time to test products is on the long rides to ensure you know when and which energy gels work best for you.

SHOULD I CONSUME WITH WATER?

It's always best to take energy gels with water, but it's not necessary with some energy gels.

Without water, some energy gels will take longer to digest and enter the bloodstream causing a delay in performance. Additionally, don't take energy gels with a sports drink unless you are consuming as part of a planned intake, the combined intake of energy gels and an energy drink puts you at risk of taking on too much sugar at once.

ENERGY GELS OR ENERGY CHEWS?

Energy gels and energy chews are both popular choices among active individuals looking for a quick and convenient source of carbohydrates to boost energy and endurance. Both products have their own benefits and drawbacks, and choosing the right one for you will depend on your personal preferences and needs.

Energy gels offer a quick and easy way to consume carbohydrates and electrolytes, but may not be suitable for those who dislike the texture or taste.

Energy chews, on the other hand, offer a more appealing taste and texture, but may take longer to consume and may not be suitable for those with dietary restrictions.

To find the best option for you, it's important to keep track of your experiences with different products, take note of what works and what doesn't, and make adjustments as needed. You can find out the major differences between energy gels and energy chews in our article here
