Cycling is full of rites of passage, whether it’s falling over sideways outside a crowded pub garden in clipless pedals or, on a more positive note, riding your first century. Somewhere along the line, you’re also likely to experience the bonk for the first time. Often memorable but never fun, it’s a need for food, or sugary drink, that goes way beyond hunger or thirst – rather, it’s a feeling of having been hollowed out and completely drained of energy.

The usual remedy involves repairing to the nearest garage forecourt and consuming your bodyweight in confection and sugary drinks. Once you’ve experienced it, you’re unlikely to forget the importance of fuelling your riding – and what happens when we don’t consume enough. The idea for sufficient energy is obvious enough, but there is a vast array of options on where exactly that energy comes from. Should we choose ‘real’ food – bananas, home-made flapjacks and the like – or pre-packaged sports nutrition, gels and powdered drinks?

A lifelong cyclist and cycling fan, James’s racing days (and most of his fitness) are now behind him. But he still rides regularly, both on the road and on the gravelly stuff. James is feeling vindicated in his lifelong faith in chocolate milkshake and sarnies.

banana in the fruit bowl? Great. One last gel in the pack? Lovely – into the back pocket it goes. Just to complicate matters, modern nutrition science is calling into question how exactly to classify foods as ‘real’ or not.

If you’re planning to fuel your ride with multiple petrol station forays, a lot of what you might be stocking up on has come to be known as UPF – ultra-processed foods. This is the sort of stuff that has long lists of ingredients, many of which are a far cry from anything you’ll find in your kitchen. This type of food comes in a packet, and is increasingly being implicated in global health concerns (see panel) – and can’t be considered ‘real’ in any meaningful sense. The same goes for almost all sports fuel products: they fall under the UPF umbrella too.

There are, of course, different reasons for choosing one type of fuel over another – among which health is only one. Expense is certainly one of the chief reasons riders might choose non-sports food. With gels costing between £1.50-£2 each, even when bought in bulk, the outlay quickly mounts. In its favour, sports fuel is widely regarded as the most efficient way to deliver high energy loads rapidly into your bloodstream, which might mean you consider it a worthwhile expense.

Ida Bergsløkken is a performance nutritionist and former performance chef at EF Education-EasyPost who advocates using both real and sports nutrition in combination. “I see real food as super important as a baseline for everyone, whether you’re a top-level [athlete] or an amateur,” Bergsløkken says. “Everyone needs a certain amount of micronutrients and with sports food, you’re just thinking about carbs, proteins and fat – you’re not necessarily getting the magnesium, zinc, B-vitamins, etc, that you need.”

On the issue of sports fuel being classified as ultra-processed, Bergsløkken emphasises that most of the food we eat should be unequivocally real. “Everyone should make a bigger effort to prepare meals using real food,” she says, “and then the [relatively small quantity of ultra-processed] sports nutrition in itself wouldn’t really be a problem.” For hard training, Bergsløkken advises that it is hard to beat dedicated sports nutrition for getting energy to the muscles as efficiently as possible.

“If you do a hard interval session, you’d not want to be trying to eat a flapjack. You would want a drink or gel. If it’s once or twice a week, its being ultra-processed is not an issue. The problem comes if you consume lots of sports drinks and gels, and then don’t eat proper food at home. If you only eat fast food meals, then you’re in for really big trouble.”

That trouble, explains Bergsløkken, may manifest in the form of sub-optimal mitochondrial health. Mitochondria are the powerhouses of the cells and crucial in athletic performance. Too many UPFs may also result in a lack of vitamins and magnesium, and the antioxidants that help buffer training stress. That’s not to say the occasional takeaway spells disaster. “In the end, what you do most is what’s going to matter,” says the nutritionist.

As most cyclists know, taste fatigue on long rides can be a real problem. After four or five hours of hoovering up the sweet stuff, many riders find themselves desperate for something savoury. This is why pro riders are often supplied not just with gels and drinks but also with savoury rice cakes or paninis. Someone who is used to prescribing fuel for the longest rides is endurance nutritionist Jill Mooney (BarrUltra.com), who concisely says, “the fastest way to a DNF is through the gut.” Though some of the riders Mooney works with do use gels and bars, she is a strong advocate of real foods, both on and off the bike.

“The meals at home are nutrition,” says Mooney, “and the food on the bike is fuel.” What is her fuel of choice for on the bike? “You can carry a few little croissants and sandwiches, but keep it simple. Jam, butter, ham, it doesn’t matter – you just want simple food that you know works for you. A banana is just a gel in a skin – it’s about 30g of carbohydrate. Any chocolate bar will do – as long as it doesn’t melt, and holds form in your pocket.” Mooney takes a similar stance on pre-made cereal bars: “Find a bar that works for you. Any bar will do, any kind of muesli bar,” she says.

Mooney makes reference to her husband Joe Barr, the veteran Northern Irish ultra-distance racer, former RAAM age category winner and World Ultra Cycling Association champion. In Joe’s multi-day epic rides, Mooney explains, he needs energy delivered at a slower and very sustainable rate – 30-40g of carbohydrate per hour, compared to the 60-90g/hr prescribed for high-intensity sessions.

carb and a little bit of protein.” Mooney recommends standard, shop-bought 1% fat chocolate milk. “If you can handle dairy, it’s brilliant,” she says. “It has a three-to-one ratio of carbohydrate to protein.” After a hard training ride, Barr downs some chocolate milk, has a shower, then tucks into a simple wholefood meal such as a tuna sandwich.

Bergsløkken is also a fan of wholefood recovery meals: “Instead of a protein shake, egg-fried rice is really simple. You can even pre-cook the rice before your ride, then just fry once you get back. Add the eggs with maybe some onions and peppers and some spinach, and then you have a meal made in five minutes.” It’s not only simple, but nutritionally optimal too. “The carbs are easily absorbed and, made with three or four eggs, you have around 20 grams of protein.”

Both of our experts come from different areas of cycle sport, but there is one thing they agree on: the importance of real, whole food meals away from the bike. Neither shies away from recommending ultra-processed options as on-bike fuel, believing that any potentially harmful effects are mitigated by a good off-bike diet.

In the end, fixating on whether to fuel with gels or flapjacks during your ride misses the bigger picture. Both have their place, and neither will make or break your performance on their own. What matters more is the quality of your everyday diet. A nutrient-dense, wholefood approach off the bike has a greater long-term impact on your training, recovery and long-term health than any mid-ride snack ever could.
