Cycling Sportive Checklist: What to Pack in Your Jersey Pockets
Three pockets. That is all you get. On a 100-mile sportive with 2,500 metres of climbing, the contents of those three pockets will decide whether you finish strong or grind the last 30 kilometres home on empty legs, swearing at every false flat. I have done both, and the difference was never fitness. It was what I packed the night before.
This is a practical guide to cycling sportive jersey pocket nutrition and kit: what goes in, how much of it, and where. It is built around the numbers that matter (carbs per hour, grams per pocket, sodium per litre) rather than vague advice to "eat little and often". Read it, lay everything out on the kitchen table the night before, and you will roll to the start line with nothing to think about but riding.
Start With the Maths: How Much Fuel Do You Actually Need?
Before you pack a single thing, work out how long you will be out. A typical UK sportive runs 80 to 160 kilometres. At an honest amateur pace of 25 km/h with stops, a 100-mile route is six to seven hours in the saddle. That is the number that drives everything else.
Current sports science is fairly settled on intake: for rides over two and a half hours, aim for 60 to 90 grams of carbohydrate per hour. Below 60g/h you will be drawing down glycogen stores faster than you replace them, and most riders have roughly 400 to 500 grams stored in muscle and liver at the start. Ride hard for three hours at 50g/h and you are already deep into the red. That is the bonk, and it arrives with no warning.
So for a six-hour sportive at 70g/h you need around 420 grams of carbohydrate on the bike, minus whatever you pick up at feed stations. Assume feed stations will give you perhaps 60 to 80 grams total (a banana, a flapjack, a cup of squash) and that you should not rely on them for anything more. That leaves roughly 340 grams to carry or drink. Split it 50/50 between bottles and pockets and you need about 170 grams of solid carbs on your person. Now you know what you are packing for.
Cycling Sportive Jersey Pocket Nutrition: The Left, Middle and Right
Every rider ends up with their own pocket system, but there is a logic to it that works. Your dominant hand reaches for the pocket on that side most easily, so that is the food pocket. The middle pocket is for things you rarely need mid-ride. The other side pocket is for layers and rubbish.
- Right pocket (food you will eat while moving): the bulk of your carbohydrate. For 170 grams of solid carbs, that is roughly 12 to 14 energy pastilles at around 12 to 13 grams of carbohydrate each, decanted into a small zip bag so you can grab two or three at a time without looking down. Add one bar for the first hour if you like something more substantial early on when your stomach is fresh.
- Middle pocket (the "hope I don't need this" pocket): a spare inner tube or tubeless plug kit, two CO2 canisters and a head, a mini tool, tyre levers, £20 in cash and a bank card, phone in a waterproof pouch. Pack this pocket tightest because it is the heaviest and you want it sitting in the small of your back, not swinging.
- Left pocket (layers and rubbish): a packable gilet or rain cape, arm warmers if you started in them, and every wrapper you generate. Keep this pocket the least stuffed so you can jam a jacket into it on a descent without stopping.
Weigh it. A well-packed jersey for a 100-miler should come in under 600 grams across all three pockets.
What Goes in the Bottles
Bottles are your second carbohydrate source and your only sodium source, so treat them as part of the nutrition plan. Two 750ml bottles is standard. In typical British conditions (15 to 18 degrees) you will sweat between 500ml and 1 litre per hour, so refill at every feed station whether the bottles are empty or not.
Mix one bottle at 6 to 8 percent carbohydrate (45 to 60 grams in 750ml) and keep the other as plain water or a light electrolyte mix. The plain bottle matters: if your gut starts to complain, you need something to dilute what is already in there. Aim for 500 to 800mg of sodium per litre in at least one bottle. Most riders under-salt and over-sugar their drinks, then wonder why they feel bloated at 80 km. Carry two electrolyte sachets in the middle pocket for refills; feed stations rarely have anything but water and squash.
Timing: The Bit Everyone Gets Wrong
You can carry the perfect amount of fuel and still blow up if you eat it at the wrong time. The most common mistake I see at sportives is riders who eat nothing for the first 90 minutes because they "feel fine", then try to catch up on a climb. Your gut cannot absorb 90 grams in one go while you are at threshold. It can absorb a steady 15 to 20 grams every 15 minutes, all day long.
- 0 to 30 minutes: nothing solid. Sip the carb bottle. Your breakfast (ideally 1 to 1.5g carbs per kg bodyweight, eaten three hours before the start) is still doing its job.
- From 30 minutes onwards: two or three pastilles every 20 minutes, or one bar in the first hour if you prefer. Set a timer on your head unit. Do not rely on hunger; by the time you feel hungry on the bike you are already 45 minutes behind.
- Before every major climb: eat on the approach, not on the climb. Chewing at 170 bpm is miserable and half of it ends up on your jersey.
- Final hour: most riders stop eating because the end is in sight. This is exactly when the last 30 grams matter most. Keep going until 20 minutes from the finish.
Practise this on long training rides. A stomach that has trained at 70g/h will handle 70g/h on the day. One that has trained at 30g/h will not.
What We Use at FTP Endurance Fuel
Our own sportive pocket is fairly boring, which is the point. The right pocket holds a zip bag of around 14 Mixed Fruit Energy Pastilles, which works out at a little over 170 grams of carbohydrate in a 1:1 glucose-to-fructose ratio. That ratio matters on long days because it uses two separate transporters in the gut, which is how you get past the roughly 60g/h ceiling that glucose alone runs into. Pastilles also do not melt in a back pocket in July and do not shatter in a back pocket in February, which is more than can be said for a lot of alternatives.
We buy in the 1kg bulk bag and decant, partly because it is cheaper per gram of carbohydrate than any single-serve packet, and partly because it means one zip bag and zero wrappers to fish out of a pocket on a descent. For the drive home there is usually a handful of the tart cherry version in the car, because the anthocyanins in Montmorency cherry are one of the few recovery aids with decent evidence behind them for reducing muscle soreness in the 48 hours after a hard effort. If you have never used pastilles on the bike, the taster pack is the sensible way to test them on a training ride before committing to a race day.
The Night-Before Checklist
Lay everything out and tick it off. It takes five minutes.
- Right pocket: 12 to 14 pastilles in a zip bag (roughly 170g carbs), one bar for hour one
- Middle pocket: tube or plug kit, two CO2 canisters and head, mini tool, levers, cash and card, phone in a waterproof pouch, two electrolyte sachets
- Left pocket: gilet or rain cape, arm warmers, empty space for wrappers
- Bottle one: 45 to 60g carbs plus 500 to 800mg sodium in 750ml
- Bottle two: plain water or light electrolyte
- Head unit: eating alert set to every 20 minutes
- Breakfast planned: 1 to 1.5g carbs per kg bodyweight, three hours before the start
Get cycling sportive jersey pocket nutrition right and the ride stops being a fight against your own energy levels and becomes what it should be: a long day out on good roads with people who like the same daft hobby you do. If you want to stock the right pocket without buying twenty individual packets, the FTP bundles are the most cost-effective way to fill it. See you at the feed station.
