Ideal for cyclists, runners and endurance athletes who prefer a smooth, refreshing gel that supplies carbohydrate without requiring water to consume it.
When your ride demands dependable fuel, SIS GO Isotonic Energy Gel delivers 22 g of carbohydrate and 87 kcal per 60 ml sachet. Its isotonic formula is designed to pass through the stomach quickly without needing extra water to dilute it, so you can take on carbohydrate without adding a bulky drink to your fuelling plan.
The liquid texture is easy to squeeze down while riding, and the pineapple flavour offers a refreshing alternative to thicker, chewier gels. Real-world testing found the gel easy to consume, pleasant tasting and comfortable on the stomach, although its relatively high fluid content means each sachet provides less carbohydrate than some concentrated gels.
Each sachet opens quickly and fits neatly into a jersey pocket, race belt or running pack. Use 1–3+ gels per hour, depending on your event and wider fuelling strategy, aiming for 60–90 g of carbohydrate per hour. With no artificial flavours and Informed Sport certification, this 30-pack is a practical option for training blocks, racing and endurance events.
