2:1 Gel

£19.99 £7.99

2:1 Gel is an energy gel formulated for optimal absorption to meet moderate and high energy demands — while remaining light, refreshing, and not overly sweet.

Glucose and Fructose Formula

The formula combines glucose (as maltodextrin) and fructose, which are absorbed via different transporters in the gut. Because each transporter has a limited capacity, relying on a single carbohydrate can slow absorption and increase the risk of gastrointestinal discomfort.

By combining these two carbohydrates in a 2:1 ratio, the 2:1 Gel allows you to absorb 60 grams (or more) of carbohydrates per hour without overloading your gut.

Flexible Dosage

Each serving provides 30 grams of carbohydrates, making it easy to scale your intake. Consume a single serving for moderate-intensity or shorter workouts. When your energy needs are higher, take multiple servings or combine with isotonic drinks to reach 60 g (or more) per hour.

The 30-gram serving size makes the 2:1 Gel ideal for gut training. It helps you gradually adapt to a higher carbohydrate intake so you can tolerate more on race day.

Baseline Hydration

Each serving contains 100 mg of sodium to help replace sweat losses and support fluid absorption. This moderate level makes it suitable for cooler conditions, for athletes with lower sodium needs, or for those obtaining electrolytes from other sources.

Light Taste

Even though the 2:1 Gel meets high-energy needs, it has a light taste that isn’t overly sweet. This makes it easier to consume hour after hour and helps prevent flavour fatigue during long workouts.

The result is a flexible energy gel that helps you match your energy intake to the demands of the day while supporting consistent absorption, gut comfort, and a long-term fuelling strategy.

  • Preserves glycogen stores
  • 2:1 ratio supports high energy intake without digestive issues
  • Prevents muscle cramps
  • Contains 100 mg of sodium to support hydration
  • Vegan, gluten-free, and free from artificial sweeteners

Consume 1–3 gels per hour, depending on your carbohydrate needs and personal tolerance. You can also combine the 2:1 Gel with isotonic drinks or energy bars to help meet your hourly carbohydrate targets.

Each serving provides 100 mg of sodium. If you’re sweating heavily, consider consuming additional sodium alongside this gel.

Q: Who should use 2:1 Gel?
2:1 Gel is designed for endurance athletes, including cyclists, runners, triathletes, and long-distance athletes. It is particularly suited for long workouts at moderate or high intensities when your body needs energy that is quickly absorbed. However, because it’s not overly concentrated, it can also be used during lower-intensity workouts.

Q: How many servings of 2:1 Gel should I take per hour?
Your carbohydrate intake should match the duration and intensity of your workout. Each 2:1 Gel provides 30 g of carbohydrates. For low- to moderate-intensity workouts lasting longer than 90 minutes, most endurance athletes aim for 30–60 g of carbohydrates per hour (1–2 servings). During moderate- to high-intensity exercise lasting over three hours, needs can increase to around 60–90 g per hour (2–3 servings). You can also combine the 2:1 Gel with drinks or bars to reach your hourly carbohydrate targets.

Q: What’s the maximum number of servings I can take per hour?
Most athletes can comfortably absorb around 60 g of carbohydrates per hour (2 gels). Athletes who are used to higher carbohydrate intake may be able to take up to 90 g per hour (3 gels). Because everyone’s body absorbs carbohydrates slightly differently, it’s best to start with 1–2 gels per hour and gradually increase if needed during training to find what works best for you.

Q: Can I use 2:1 Gel during races?
Yes. The 2:1 glucose-to-fructose ratio supports higher carbohydrate absorption than single-carbohydrate gels, making it suitable for long races with high energy demands. The 2:1 ratio also helps reduce the risk of gastrointestinal discomfort when racing at high intensities.

Q: Why does the 2:1 ratio matter?
The 2:1 glucose-to-fructose ratio is important because glucose and fructose are absorbed in the gut via different transporters. Each transporter has a limit to how much it can absorb. On average, most people can absorb a maximum of 60 g of glucose and an additional 30 g of fructose per hour. By combining these carbohydrates in the right ratio, the 2:1 Gel allows you to absorb more total carbohydrates, helping provide steady energy and reducing the risk of stomach discomfort during long or intense sessions. However, these numbers aren’t fixed. Because everyone’s digestive system absorbs carbohydrates a little differently, individual tolerance may vary.

Q: Which is better, a 2:1 or a 1:0.8 glucose-to-fructose ratio?
Both ratios are designed to take advantage of how the body absorbs glucose and fructose through different gut transporters, allowing you to take in more carbohydrates per hour with less risk of stomach discomfort. However, everyone’s digestive system digests carbohydrates slightly differently, so some athletes tolerate the 2:1 ratio better, while others prefer the 1:0.8 ratio. The 2:1 ratio contains slightly less fructose, making it less sweet, whereas the 1:0.8 ratio is a bit sweeter. Ultimately, the best choice comes down to your personal preference and what your body tolerates better.

Q: Can I use this gel for gut training?
Yes. Each serving contains 30 g of carbohydrates, an amount that makes it easy to gradually increase intake over time. This helps your digestive system adapt so you can tolerate higher carbohydrate intake on race day.

Q: Why does this gel contain only 100 mg of sodium?
The 2:1 Gel is designed as a flexible energy gel with moderate sodium levels. It works well in cooler conditions, for athletes with lower sweat sodium losses, or when you’re getting additional electrolytes from other products.

Q: Should I add extra sodium when using this gel?
If you sweat heavily, train in hot conditions, or are prone to cramping, additional sodium may be helpful. You can combine this gel with electrolyte or sodium products to meet your individual needs.

Q: Can I combine 2:1 Gel with drinks or bars?
Yes. Many athletes combine gels with drinks or bars to reach higher hourly carbohydrate, sodium, and fluid targets. For optimal gut comfort and absorption, we recommend pairing it with other products that have a 2:1 glucose-to-fructose ratio.

Q: Why does the nutrition label say that 2:1 Gel only contains 22 g of sugar?
Because not all carbohydrates in the 2:1 Gel come from sugars. A significant portion of the carbohydrates is provided as maltodextrin, which is not classified as a sugar on nutrition labels. When combined with fructose, this allows the gel to deliver a total of 30 grams of carbohydrates, even though the nutrition label states a lower sugar content.

Nur zu empfehlen!

Ich habe viele Gels probiert aber keins war so lecker wie dieses.
Die Verträglichkeit ist hervorragend, die Einnahme war easy, Geschmack war so wie ich es mir vorgestellt habe.
Ich werde mir jetzt noch Blutorange bestellen und hoffe das dieser Geschmack genau so gut ist.

Muy bien pero mejor sin sabor

Los he probado en entrenamientos de 3-4h y se toleran relativamente bien, pero en carreras largas 7h+ el sabor cansa y a nivel digestivo acaba produciendo acidez, el combo 30gCH y 100mgNA me parece perfecto pero falla en sabor, por lo menos en mi.
