HIGH5 Caffeine Gels are a solid choice in the sports nutrition space, and at this price they're nearly a no-brainer for serious endurance athletes. Here's what you're getting: twenty 40-gram sachets designed specifically for runners, cyclists, and ultra-distance folk. Each one delivers fast-acting glucose plus caffeine for that dual energy punch—glucose for immediate fuel, caffeine for mental sharpness and fatigue management during those long efforts.
What makes these stand out is the natural fruit juice base. Too many energy gels taste like you're sucking on a plastic tube; these actually taste decent, which matters when you're forcing down gels every 45 minutes. The orange flavour is pleasant without being sickly. They're also easy to carry, easy to consume on the move, and digest reasonably well—no stomach complaints from my testing.
The caffeine content is moderate (roughly 40mg per gel), so whilst they won't give you the jolt of a strong coffee, they work perfectly for sustained efforts rather than explosive power. They're particularly good for ultra-marathons, Ironman prep, or long cycling days where you need consistent fuelling without overdoing the stimulants.
The main consideration: at 40g, they're slightly smaller than some competitors' offerings, though the price more than compensates. If you're doing back-to-back intense sessions weekly, you might find yourself rotating stock quickly. For casual runners, these last ages.
At £7.91, this is genuinely one of the better prices I've seen on name-brand sports gels. Full-priced, they're premium; at this discount, they're an absolute steal. If you're training seriously for anything endurance-related, grab them now.
