Best Energy Gels for Long Bike Rides: 60g, 90g and 120g Carb Strategies

Nobody staring down a four-hour ride is wondering what an energy gel does. They are wondering how many to buy, how to space them out, and whether it is cheaper to lean on drink mix instead.

The simplest way to answer that is to start from total carbohydrate needed, then work backwards to a shopping list. Sports nutrition guidance generally lands in this range for ride duration:

These are population-level ranges, not a prescription — gut tolerance, training status and heat all shift the practical number. They are, however, a far more useful starting point than picking gels because the flavour sounded nice.

Gels are convenient, not compulsory. A sensible long-ride carb strategy usually blends three sources:

• Drink mix (roughly 40-90g carbs per bottle depending on concentration) — the easiest way to get a steady baseline without chewing.
• Gels (20-40g carbs each depending on brand) — quick top-ups, easy to eat while climbing or in traffic.
• Real food — bananas, rice cakes, malt loaf, dried fruit — cheaper per gram of carbohydrate and a break from sweetness, though slower to digest under hard effort.

A blend also spreads gut load across different absorption pathways instead of relying on one gel brand's formula for six straight hours.

A single 6-hour day built entirely from premium hydrogel gels can run £15-£20 in gels alone. Swapping in drink mix and real food for a third of that carbohydrate typically cuts the bill by a third to a half without changing the total grams delivered. For riders doing this most weekends through a season, that difference is worth planning around rather than discovering at the till.
