Depending on the distance, you should consume 1-3 gels every hour to reach an 80g-120g target intake. In some cases, such as in cold weather, it may be necessary to consume more. They are easy to tear open and consume. Remember to pop the packaging in your pocket.

Ultra Running Fuelling

Energy is essential for all types of running, but it’s crucial for ultra running. Ultra-distance runs demand the highest level of physical and mental performance from runners – so fuel up before you hit the trail! With this guide, you’ll be well on your way to finding the perfect energy gels, bars and snacks to help take your ultra running to the next level.

The Science Behind Energy Gels

The primary purpose of energy gels is to provide an easily digestible carbohydrate source for athletes during their long-duration activities. During these more extended events, the body begins to run out of its stored glycogen, and therefore energy gels are designed to replenish this depleted energy source quickly and effectively. Studies have shown that energy gels can help both physiological and psychological performance.

Most energy gels contain maltodextrin and fructose as their primary carbohydrate sources. Maltodextrin is a complex carb that provides a more sustained release of carbs than simple sugars and helps regulate blood sugar levels while running. Fructose is a simple sugar that is easy to digest and helps get glucose into your muscles faster. Some energy gels also provide essential electrolytes such as sodium and potassium, which help replace lost minerals during exercise.

Energy Gels, Bars & Snacks: Eat Little But Often

When it comes to fueling for ultra running, the key is to eat little but often. Doing so means ensuring you’re getting the right amount of energy from your gels, bars and snacks throughout your run – so don’t forget to keep a few stashed in your pack or pockets! Regular fuel intake and sipping sports drinks while you run can also help you maintain optimum performance and stay energised until the finish line.

Take Advantage Of Aid Station Food

Eating And Drinking At Aid Stations

If you’re running an ultra marathon with aid stations, take advantage of the food they provide. This can include everything from sandwiches and bars to chips, gels and sports drinks. Aim to eat something small every 30–45 minutes during your run – this will help keep your energy levels up and prevent any bonking!

What Is Bonking?

Bonking, also known as hitting the wall, is a term used to describe what happens when your body runs out of glycogen and can no longer sustain itself with energy. The Bonking phase typically occurs after several hours of intense physical activity or on longer runs when you need more fuel. To avoid this dreaded situation, ensure you regularly eat during your run and take sufficient energy from gels, bars and snacks.

Best Forms Of Energy For Ultra Running

carbohydrates for athletes

Different forms of energy fuel our bodies in different ways, so it’s essential to identify the best energy foods for your needs when preparing for an ultra run. Complex carbohydrates that provide sustained energy are great for runs lasting several hours or more as they will keep you fueled for longer. If you are running your first ultramarathon, then make your gels, bars and snacks with you on training runs. This will allow you to learn what works best for you and what your body can handle after 4 or 5 hours of physical exercise. You should train with your fuel, just like you would with other gear like race running socks, trail running poles and hydration running packs.

High-GI foods can also be beneficial during shorter races, as these provide a quick boost of energy absorbed quickly by the body. What about protein? Protein is essential for muscle repair and growth, so include some protein in your diet before, during and after a race. Will a little bit of fat help too? Yes, “good fats” like avocado and nuts also provide essential nutrients and fatty acids for optimal running performance.

Final Thoughts & Summary

No matter what kind of ultra running you’re doing, having a good supply of energy gels, bars, and snacks on hand is essential! Doing so helps you keep pushing along the trail and gives you that extra energy to keep moving. Fueling is a must, not an optional extra, for most ultra events. Think of it as an investment in your performance and ensure you are prepared with the proper fuel to help you reach your goal.

Try experimenting with different brands, energy sources and textures and find out what is best for you. If you are participating in an ultra event, remember to check with the organisers what food and drink are available at the aid stations. Being used to eating various sources of energy will help you plan your refuelling strategy and ensure you are well-prepared for the challenge ahead.
