Cycling Nutrition for a Multi-Day Tour or Bikepacking Trip
Riding hard for one day is a fuelling problem you can solve with a jersey pocket and a bit of luck. Riding hard for five days in a row is a completely different problem, and it is the one that catches most people out. On day one you feel unstoppable. By the afternoon of day three you are pushing 40 watts less for the same heart rate, your legs feel hollow rather than sore, and you have started fantasising about a bakery instead of the view. That is not ordinary fatigue. That is a carbohydrate deficit that has been compounding quietly since Monday morning.
The maths is brutal and worth facing head-on. A loaded touring bike on rolling terrain burns roughly 400–700 kcal an hour depending on your weight, the gradient and how much gear you are hauling. Six hours in the saddle is therefore 2,400 to 4,200 kcal on top of the 1,600 to 2,200 kcal your body needs simply to exist. Your total muscle and liver glycogen stores hold around 400–500g of carbohydrate, or roughly 1,600 to 2,000 kcal. Miss your daily target by 800 kcal and you will have drained that reserve entirely by the end of day three. Getting cycling nutrition for a multi-day tour right is not about heroics on any single day — it is about never letting that gap open in the first place.
Work out your daily energy cost before you leave
Guessing is what sinks tours. Spend ten minutes before you go and estimate properly. Take your resting requirement — roughly 22 kcal per kg of body weight per day for most riders, so around 1,700 kcal for a 75kg cyclist — and add your riding cost. A reasonable working figure for loaded touring at endurance pace is 8–10 kcal per kilometre on rolling terrain and 12–14 kcal per kilometre in genuinely mountainous country with 1,500m or more of climbing.
A 120km day over a couple of Alpine passes therefore lands somewhere near 5,000–5,500 kcal in total. That is a lot of food, and the single most common mistake on tour is assuming you will simply eat it because you are hungry. You will not. Appetite is blunted for two to three hours after hard riding, which is precisely the window in which you most need to be eating. Deliberate fuelling beats intuitive eating every time on a multi-day trip.
Split the target roughly into thirds: about one third consumed on the bike, one third in the two hours after you stop, and one third across breakfast and the evening meal. If any one of those three legs collapses, the day is in deficit.
Cycling nutrition for a multi-day tour: the on-bike numbers
Race-day advice tells you to take 60–90g of carbohydrate an hour, and for a one-off effort that is correct. On a multi-day tour the intensity is lower but the duration is far longer, so the sensible range is 40–60g an hour for steady touring and 60–90g an hour on hard climbing days or when you are chasing a ferry.
Carbohydrate type matters more than most riders realise. A single glucose-based fuel saturates the SGLT1 intestinal transporter at around 60g an hour, and everything above that sits in your gut. Combining glucose with fructose recruits a second transporter (GLUT5) and lifts the ceiling towards 90–120g an hour. That is why a mixed-source fuel is worth choosing over a pure maltodextrin product on big days.
Fluid and sodium are the other half of the equation. Sweat sodium losses vary enormously between individuals — anywhere from 400 to 1,800mg per litre — and over five consecutive days those losses accumulate. Aim for 500–700ml of fluid an hour in mild conditions and closer to a litre in heat, with 500–800mg of sodium per litre. Persistent headaches and unusually salty crusting on your kit are the practical signals that you are under-replacing.
The overnight refuel is where tours are won
Everything you do between finishing on Tuesday and starting on Wednesday determines how Wednesday feels. When the recovery window is shorter than eight hours, the research points to 1.0–1.2g of carbohydrate per kg of body weight per hour for the first four hours after riding. For a 75kg cyclist that is 75–90g an hour — a substantial meal plus deliberate snacking, not a single recovery shake.
Protein is not optional either. Around 0.3g per kg per dose (roughly 20–25g) every three to four hours supports the repair work, with a daily total near 1.6g per kg. Include a dose before bed if you can; overnight is when a lot of the adaptation happens.
Sleep quality is the underrated variable on tour. You are in a tent or an unfamiliar bed, your core temperature is elevated, and your legs are twitching. This is where tart cherry has a genuine evidence base rather than marketing gloss: Montmorency cherries are unusually rich in anthocyanins, the polyphenols that reduce exercise-induced oxidative stress, and they also contain naturally occurring melatonin. Studies on consecutive-day endurance efforts have shown reduced markers of muscle damage and modest improvements in sleep duration when tart cherry is taken across the whole block rather than as a one-off dose afterwards.
Carrying calories when you cannot resupply
On a supported tour through populated country, food is a logistics problem you solve with a card and a bakery. On a remote bikepacking route it becomes a weight and volume problem. The metric that matters is calorie density: aim for at least 4 kcal per gram of food carried. Olive oil and nut butters hit 8–9 kcal per gram, nuts around 6, dried fruit and concentrated carbohydrate around 3.5–4. Fresh fruit, at under 1 kcal per gram, is mostly water you are pedalling uphill.
Build the load in layers. Dense, calorie-heavy items go in the frame bag for camp. Immediately accessible carbohydrate — the stuff you eat every 30 minutes without stopping — lives on the top tube or in a pocket. Genuine cycling nutrition for a multi-day tour means solving both problems at once, and the on-bike layer is the one people skimp on because it feels fiddly to organise.
One practical warning: flavour fatigue is real and it will wreck your intake by day three. If everything you carry tastes of the same synthetic orange, you will simply stop eating it. Carry at least two distinct flavours and rotate them deliberately.
What we use at FTP Endurance Fuel
Our own multi-day setup is deliberately simple. On the bike we run energy pastilles rather than gels, because they are easy to pace — you can take two every twenty minutes rather than committing to 25g of gel in one hit — and because there is no foil sachet to stuff back in a pocket at the top of a climb. Our Mixed Fruit Pastilles handle the flavour-fatigue problem well on long trips because the flavour changes as you work through the bag.
For a second flavour we add Tart Cherry Pastilles, which are tart cherry flavoured. Buying the 1kg packs and decanting into small resealable bags before you leave is far cheaper per gram of carbohydrate than individual sachets, and it lets you tune exactly how much goes in each bag for each day. If you would rather test the texture on a couple of training rides before committing to a whole tour's worth, the taster pack is the sensible starting point. If you want real Montmorency tart cherry across a consecutive-day block, it's in Power Fluids (3g per serving).
Nothing about multi-day fuelling is complicated, but all of it requires planning you do at the kitchen table rather than at the roadside. Work out the daily cost, split it into thirds, protect the on-bike layer, and treat the overnight refuel as part of the ride rather than something that happens afterwards. Do that and day five feels like day one — which, when you are somewhere genuinely beautiful with a week's riding ahead of you, is the entire point. Plan your fuelling before your next tour and browse our bundles to work out what to pack.
