Walk into any cycling shop and you'll see shelves of gels, bars, electrolyte tablets, and recovery drinks. The packaging implies that without all of this, you'll bonk (run out of energy) catastrophically and fail. This sells a lot of products. It's also, for most beginner cyclists, completely unnecessary.
The truth about nutrition for beginner cyclists is far simpler than the industry wants you to believe. Here's what you actually need.
Short rides (under 60 minutes): water is enough
For rides under 60 minutes at moderate intensity, your body's existing energy stores are more than adequate. You don't need to eat before, during, or immediately after a short ride. Just drink water — roughly 500ml per hour is a sensible baseline, more in hot weather or if you sweat heavily.
Dehydration affects performance before you feel thirsty, so starting a ride with a glass of water and carrying a bottle with you is good practice. But you don't need sports drinks, electrolyte tablets, or anything beyond water for short sessions.
Medium rides (60–90 minutes): a little more thought
For rides of an hour to an hour and a half, the main consideration is what you've eaten in the hours before. If you're riding mid-morning and had breakfast, you're almost certainly fine. If you're riding first thing in the morning on an empty stomach, a light snack 30–60 minutes before — a banana, some toast, a small bowl of porridge — gives you a bit of energy to work with.
During the ride itself, keep drinking. A 750ml bottle is usually enough for this duration. You probably won't need to eat during the ride, but there's no harm in pocketing a banana or cereal bar if you feel better knowing it's there.
Eat normally throughout the day. Drink water before and during rides. For anything over 90 minutes, bring a snack. That's genuinely 90% of cycling nutrition sorted.
Longer rides (90+ minutes): the bonk is real
Once you start riding for 90 minutes or more, nutrition becomes more important. "Bonking" — the cycling term for running out of readily available energy — is a real and rather unpleasant experience. Your legs feel suddenly hollow, your mood crashes, and you feel like you can't pedal anymore. It's your body's glycogen stores running empty.
For longer rides, the practical solution is simple: eat little and often during the ride. A small snack every 45–60 minutes keeps your energy levels stable. The best foods are carbohydrate-rich, easy to eat on a bike, and not too heavy: bananas, dates, dried mango, rice cakes, cereal bars, or yes — if you like them — energy gels.
Gels are just concentrated carbohydrates in a packet. They're not magic, and they're not necessary — real food works just as well or better for most beginner riders. The advantage of gels is convenience; you can eat them with one hand while riding without worrying about dropping anything. But a banana from your jersey pocket achieves the same purpose.
What to eat after a ride
Recovery nutrition matters more as rides get longer. The basic principle: in the 30–60 minutes after a ride of 90 minutes or more, eating a combination of carbohydrate and protein helps your muscles repair and replenish their energy stores. This doesn't have to be complicated — a glass of milk with a banana, some yoghurt and fruit, eggs on toast, or a meal with rice or pasta and protein all work perfectly.
For shorter rides, you can simply eat your next normal meal and be fine. You don't need a recovery shake after a 45-minute spin.
Hydration in more detail
On longer rides in warm weather, plain water isn't the whole story. When you sweat heavily for extended periods, you also lose electrolytes — primarily sodium — and these need replacing. The symptoms of significant electrolyte depletion include cramps, headaches, and nausea.
For most beginner cyclists on rides under two hours, eating salty foods (your normal diet usually provides plenty of sodium) and drinking water is adequate. If you're doing your first really long summer ride and sweating a lot, adding an electrolyte tablet to your water bottle is cheap insurance. But you don't need it for regular training.
Sports drinks: necessary or marketing?
Sports drinks are a legitimate tool for long, intense sessions — they combine hydration and carbohydrates efficiently. For beginner cyclists on normal training rides, they're mostly unnecessary and add extra sugar to your diet without meaningful benefit. Water, food, and common sense are a much better starting point.
The main thing
Don't let nutrition complexity stop you from riding. The number of people who have given up or delayed cycling because they weren't sure what to eat is too many. The answer is almost always: eat normally, drink water, and take a snack if it's going to be a long one. Your body is smarter than you think.
