Running Gels
Running Gels
Running gels are small sachets of concentrated carbohydrate you take during long runs, rides and races to keep fuel coming in. Our range is from Science in Sport (SiS): GO Isotonic Energy Gels, which are designed to be taken without water, and GO Energy + Caffeine gels for when you also want a caffeine hit.

Running Gels: buying guide
How gels work
The Australian Institute of Sport (AIS) describes sports gels as a highly concentrated carbohydrate source, usually 20 to 30 g per sachet, with a texture that is easy to swallow on the move. Most gels should be taken with water, but a small number labelled isotonic, such as SiS GO Isotonic, are designed to be taken without it. Each GO Isotonic gel provides 22 g of carbohydrate in a 60 ml sachet.
How much do you need?
The AIS guidance on carbohydrate during exercise:
- Under 45 minutes: not needed.
- 45 to 75 minutes at high intensity: small amounts, or even a carbohydrate mouth rinse.
- 1 to 2.5 hours: 30 to 60 g per hour, or roughly one and a half to three GO Isotonic gels.
- Longer than 2.5 to 3 hours: up to 90 g per hour.
The AIS notes that glucose-based carbohydrate above about 60 g an hour does not add benefit and can upset the gut, so check the type of carbohydrate if you plan to take more.
Caffeine gels
The AIS says some gels contain 25 to 100 mg of caffeine. SiS GO Energy + Caffeine provides 75 mg per gel in Berry and 150 mg in Double Espresso, alongside 22 g of carbohydrate. Count these with coffee and any pre-workout. For drug-tested athletes, SiS states that its products are Informed Sport approved. Choose batch-tested products like this and check with your sport.
Tips for race day
- Practise in training first. The AIS recommends testing gels before competition and building up gradually.
- Drink enough fluid with non-isotonic gels to reduce the risk of gut upset.
- Protect your teeth: rinse with water afterwards and wait at least 30 minutes before brushing, as the AIS advises.
- If you have fructose malabsorption or follow a low FODMAP diet, check the carbohydrate sources on the label.
