Energy Gel Caffeine 20 x 40g for Portable Energy During Endurance Training and Racing

HIGH5 Energy Gel Caffeine delivers 23g of carbohydrates, 91kcal and 30mg caffeine per 40g sachet, with 2.8g of sugars from a maltodextrin and fructose base. The standard-concentrate format provides a thick, compact gel. The 20-sachet pack covers 20 individual on-the-move servings.

Carbohydrates from maltodextrin and fructose provide both glucose-pathway and fructose-pathway oxidation - the same dual-transporter approach HIGH5 applies across its endurance range. At 23g carbohydrates per sachet and a typical endurance intake of 60-90g per hour, athletes consuming two to three gels per hour hit the upper range of the research-supported absorption window. Caffeine at 30mg contributes to alertness and concentration - modest enough for mid-race use without the potential for overstimulation on an already-elevated heart rate.

The 40g sachet is the standard endurance gel format: compact enough to fit multiple sachets in a jersey pocket or race belt, with enough carbohydrate per serve to make an impact without requiring large volumes. The compact size versus the Aqua 66g variant makes this the choice for athletes who carry water separately and prefer a more concentrated carbohydrate hit per sachet consumed.

Built for runners, cyclists and triathletes racing or training for more than 60 minutes who want a portable, compact carbohydrate and caffeine gel. Best consumed with a small amount of water to support gastric emptying at race intensity. No major allergens declared. Contains caffeine - not suitable for children or pregnant women.

Bulk alternative: Efectiv Nutrition Carb Powder 500g (19g carbs at 76kcal per 20g serving, dextrose-fructose blend) for trainees wanting bulk carb fuel rather than gel sachets.

Key Benefits

Fast Carbohydrate Fuel

23g of readily absorbed carbohydrates per gel maintains energy and delays fatigue during endurance training and racing.

Strategic Caffeine

30mg per gel gives you control over your caffeine intake across a session - use early, mid or late depending on your race plan.

Compact & Portable

40g sachets are smaller and lighter than Aqua gels - easy to pocket multiple sachets for long sessions.
