You know the feeling. The ride starts well, the legs are good, the trail is dry enough, and you're moving nicely through the first climb. Then somewhere past the point where turning back sounds worse than pushing on, the power disappears. Not gradually either. One minute you're riding. The next, you're grinding the easiest gear you've got and wondering why a trail you normally enjoy suddenly feels cruel.

That happens to plenty of riders around Nelson and across New Zealand. It isn't always a fitness problem. Often, it's fuelling. Technical riding hides it for a while because you're focused on line choice, braking points, roots, ruts, and timing. By the time you notice the drop, you're already behind. That's why energy gels have become a standard bit of kit for long trail rides, enduro days, and any session where a bottle and a banana alone won't carry you through.

That Feeling When the Tank Runs Empty

Halfway up a long climb, the warning signs are obvious if you know them. Your cadence falls off. You stop making clean decisions. Tight switchbacks feel harder than they should. Even your hands can feel a bit useless on the bars. Riders call it bonking, and if you've done enough hours on an MTB in NZ, you've probably met it already.

On local trails, it often shows up at the worst time. Not on a smooth road spin where you can sit up and coast for a bit. It hits on rocky traverses, punchy climbs, or just before a descent where you need your head switched on. That's the nasty part. Low fuel doesn't just make you slower. It can make you sloppy.

Why mountain bikers get caught out

Mountain biking is stop-start, technical, and deceptive. You might not feel like you're doing a steady endurance effort, but your body is still burning through fuel. Add Nelson's variable conditions, cool starts, warm afternoons, wind, damp bush sections, and long trail access climbs, and it's easy to under-eat without realising it.

A lot of riders also carry habits over from shorter rides. They'll eat breakfast, throw a bottle on the bike, maybe tuck a bar into a pocket, and assume that's enough. Sometimes it is. Often it isn't.

Practical rule: If your ride has enough climbing or intensity that you're thinking about pacing, you should also be thinking about fuelling.

Energy gels are the simple fix because they're compact, quick to use, and easy to carry. They're not a magic product. They're just one of the cleanest ways to get usable carbs into your system before the wheels really come off.

If you also train in different states of fuelling, there's a useful fasted weight training guide that explains where training without food can make sense and where it usually backfires. For trail riding, especially hard or long trail riding, under-fuelling is rarely the clever option.

What Are Gels and How Do They Actually Work

An energy gel is basically a concentrated carbohydrate source in a small packet. That's the short version. The useful version is this. It gives you fuel in a form that's easier to carry and easier to get down mid-ride than most solid food.

The wider category is growing fast. The global energy gel market report from Credence Research says the market was valued at USD 945 million in 2024 and is projected to reach USD 1,716.9 million by 2032, a 7.75% CAGR. That growth is tied to endurance sport demand, which makes sense if you've spent any time around NZ cyclists, runners, and trail communities.

The simple version

Your body runs well on carbohydrate when the pace is up. On an easy cruise, you've got more room to rely on normal meals and a slower drip-feed of energy. On a hard climb, repeated punchy efforts, or a race stage, you need something that gets to work quickly.

That's where gels fit. They're the on-bike version of convenience fuel.

Consider this:

• Real food works well before the ride: porridge, toast, rice, or a proper meal give you a solid base.
• Gels work well during the ride: they're made for moments when stopping to chew isn't practical.
• They help keep effort steady: instead of waiting until you're drained, you top up while you're still riding well.

What's usually inside

Most gels are built around carbohydrate sources that absorb at different rates. You'll often see ingredients such as glucose, fructose, or maltodextrin. You don't need to obsess over the chemistry, but the blend matters because it affects how well a gel goes down and how well you tolerate multiple serves over a longer ride.

Some also include sodium. Some include caffeine. Some are very thin and easy to swallow. Others are thick enough that they feel like dessert gone wrong if you try to neck one while breathing through your eyeballs on a climb.

A good gel should be boring in the best possible way. Easy to open, easy to swallow, and easy on the gut.

That last point matters. Plenty of riders don't struggle with energy gels themselves. They struggle with the wrong texture, the wrong sweetness, or using them badly. If you've had stomach issues before, it's worth reading a solid breakdown of gut-friendly energy gels and then testing a few options in training rather than guessing on race day.

Why they suit MTB better than many riders think

Road riders can often eat more predictably because they have smoother terrain and steadier pacing. Mountain bikers don't. On technical trails, you miss feeding windows. You put off eating because both hands are busy. Then you suddenly need fuel right now.

That's why energy gels NZ riders carry aren't just for racing snakes. They're practical trail tools for anyone doing rides long enough, hard enough, or remote enough that a bad energy dip can spoil the day.

Choosing the Right Gel for NZ Trails

Not all gels suit all rides. A short evening spin on familiar singletrack doesn't ask the same questions as a long backcountry mission, an enduro practice day, or a humid summer pedal where you're sweating far more than you expected.

The easiest way to choose is to stop thinking in brands first and think in ride demands first.

Start with the carb source

One of the better signs on a packet is a dual-source carbohydrate blend. NZ-based options already reflect that. Pure Sports Nutrition's gel range uses real Manuka honey alongside maltodextrin and fructose, delivering around 30g of carbs per 60g gel, which aligns with the 30 to 60g per hour benchmark for endurance exercise.

That matters because dual-source blends tend to make more sense when you're fuelling repeatedly over time. For MTB, that's useful on long fireroad climbs, stage days, and rides where intensity comes in waves rather than one constant tempo.

Then think about how you actually ride

A thick gel can be fine if you stop to take it. It can be hopeless if you try to use it while rolling into rough terrain. A very sweet flavour might taste good in the car park and turn sickly by the second hour. Caffeine can sharpen you up late in a ride, but it can also be the wrong call if you're already a bit edgy or your stomach is touchy.

Here's a practical way to compare them.

Energy Gel Feature Comparison

What works and what usually doesn't

A few patterns show up again and again on NZ trails.

• For enduro and technical trail riding: thinner gels or easy-open packets are usually less annoying.
• For long steady missions: mild flavours beat novelty flavours. Nobody wants dessert-level sweetness four hours in.
• For summer riding: sodium matters more than many riders think.
• For caffeine: use it deliberately, not because the packet looked fast.

If a gel tastes great in your kitchen but turns your stomach on a hard climb, it's not the right gel for you.

The best setup for many riders isn't one product. It's a mix. A standard gel for early fuelling, maybe a caffeinated one later, and actual fluids sorted properly so the whole plan doesn't fall apart.

Your NZ Fuelling Strategy Dosing and Timing

Good fuelling is mostly about timing. The riders who get this right don't wait until they feel empty. They start before the dip.

That matters even more in NZ riding because conditions can trick you. Cool mornings in the bush can blunt thirst. Technical terrain can make you forget to eat. Windy exposed sections can dry you out without the obvious heat stress you'd notice on a roasting road ride.

The baseline plan

For a lot of riders, a sensible starting point is simple:

1. Eat properly before the ride. Don't expect gels to rescue a bad pre-ride setup.
2. Take your first gel before you feel flat. Early is usually better than late.
3. Keep fuelling at regular intervals. Long gaps are where the wheels wobble.
4. Always pair gels with water. That's essential for most riders.
5. Test the plan in training. Race day is not the time to discover your gut hates a certain flavour or texture.

What the numbers mean on the trail

NZ-specific guidance for harder riding is a useful reality check. In the NZ cycling fuelling discussion linked here, standard advice of one gel every 30 to 45 minutes works out to about 29g of carbs per hour. For elite NZ cyclists in hard local conditions, that can sit well below the 60 to 90g of carbs per hour and 1000 to 2000mg sodium per hour needed in high-intensity events, which is why some riders need 2 to 3 gels per hour plus electrolyte drinks.

Most trail riders don't need to copy an elite race plan. But the lesson is clear. One lonely gel in your pocket isn't a fuelling strategy.

Water is part of the gel

Plenty of riders get it wrong. They treat the gel as the whole answer, then wash it down with sports drink or nothing at all. In cooler Nelson conditions, that mistake is common because you might not feel especially thirsty. Your gut still notices.

If you're carrying your bottles on the bike, a secure storage setup helps. A water bottle bag for bikepacking and trail use makes it easier to keep water accessible rather than buried in a pack where you forget about it.

Don't take a gel and hope your stomach sorts it out later. Give it water and make digestion easier on yourself.

Match the strategy to the ride

Different rides need different approaches.

• Short, hard trail laps: you may only need one gel, but timing matters. Take it before the fade.
• Long weekend rides: use gels as part of a broader plan with water and some solid food if that suits you.
• Enduro race days: think across the whole day, not just one stage. Waiting until a liaison climb has already emptied you is too late.
• Cool-weather rides: drink deliberately because thirst can lag well behind what you need.

Practice beats theory

The cleanest plan on paper still needs field testing. Use training rides to answer questions. Can you open the packet with gloves on. Does the flavour stay tolerable after a few hours. Can you stomach it under pressure. Do you remember to drink enough with it.

If not, change the system. The best fuelling strategy is the one you'll use when you're tired, muddy, and thinking about the next section of trail rather than nutrition.

Practical On-Trail Tips Storage and Waste

A gel that lives in the bottom of your pack under a tube, jacket, and mini pump might as well be at home. Access matters. If it takes too much effort to get to, you'll delay using it, and then you're back to chasing your energy rather than staying ahead of it.

Carry it where you can reach it

Jersey pockets work. Hip packs work. Top tube storage works. The right answer depends on the ride and what else you're carrying.

A few practical options:

• Jersey pocket: good for quick access, but not ideal if you also cram in tools and wrappers.
• Top tube storage: handy for race days and easier to grab on smoother sections.
• Hip pack or vest pocket: useful when you want better organisation and less bouncing.
• Hydration pack setup: if you're carrying more gear, it helps to organise fuel where it won't disappear into the void. A good hydration bladder setup for MTB riding makes long rides less chaotic.

Learn to use them before it matters

Opening a gel cleanly while riding is a skill, not a personality trait. Tear from the corner before the rough stuff if you know a feed is coming up. If the packet is stubborn, stop for five seconds rather than spraying sticky syrup over your gloves, stem, and front brake lever.

What usually works:

• Pre-stage prep: tear the top slightly before you roll if you know you'll want it soon.
• Take it on a calmer section: not in the middle of roots, rock gardens, or switchbacks.
• Empty it fully: half-finished gels are annoying, sticky, and easy to lose.

Tuck the empty wrapper straight back into the pocket you took it from. Don't trust yourself to “deal with it later”.

Keep the trail clean

Nobody wants to see gel tabs and sticky packets on the side of a track. NZ riding culture is pretty clear on this. If you bring it in, take it out.

Refillable soft flasks are also worth a look if you ride often and hate the waste. They're tidier, easier to customise, and can be a smart option for riders who already know exactly what type of gel consistency they like.

Sourcing Your Gels in New Zealand

You notice this one when race week is close, the weather has turned, and the gels you ordered from overseas are still somewhere between a warehouse and the border. For NZ riders, that is more than an annoyance. It can leave you changing your fuelling plan at the last minute, or lining up with products you have not tested properly on trail.

Energy gels are an established part of local sports nutrition, not some niche product you need to chase from offshore sellers. That matters because NZ mountain biking is hard on half-baked plans. Conditions change quickly, rides often mix long climbs with punchy technical work, and you want fuel you can replace easily if a training block goes well and you burn through your stash faster than expected.

The import problem riders find out about too late

The main risk is not flavour choice or price. It is whether the product gets through cleanly and arrives in time.

Imported nutrition can run into biosecurity issues, and ingredient lists matter more than riders expect. In the NZ traveller discussion linked in this biosecurity Facebook thread, people specifically raise problems with products containing ingredients such as honey. If you are ordering for an event, a stage race, or a big weekend away, that is a poor time to discover your gel is sitting in limbo.

I see riders get caught by this because overseas advice usually talks about carb grams, caffeine, and flavour fatigue. Fair enough. But for NZ buyers, availability is part of product choice. A gel that suits you on paper is no use if it turns into a border headache or arrives after the ride block you bought it for.

Why buying in NZ is usually the better call

Local stock is simpler. You know it is already here, you can reorder quickly, and you can ask someone who understands the difference between a hot gravel grind in summer and a cold, stop-start winter trail ride in the bush.

That local context matters. A road runner taking a gel every half hour on steady terrain has a different problem from a mountain biker trying to fuel around steep pinches, awkward descents, trail stops, and weather that can swing from warm to bitter in one ride. The best shop advice reflects that. It helps you choose a gel that fits how you ride, what your stomach tolerates, and how you carry water and tools. If you are still sorting that side of the setup, this guide to choosing a hydration pack for NZ mountain biking is worth a look.

A few things make local buying practical:

• Reliable supply: easier to top up before a race, trip, or big training weekend.
• Fewer surprises: less chance of ingredient issues, shipping delays, or customs hold-ups.
• Better advice: NZ bike and nutrition shops see what riders use on real trails here.
• Easier testing: you can buy a few options, try them in training, and settle on one system.

Cheap gels from offshore are not always cheap once freight, delay, and risk are added in.

For most riders, the smart move is pretty plain. Buy in NZ, test your gels on normal rides, and keep a spare stock at home so one delayed parcel does not throw your whole fuelling plan off.

Fuel Smart and Shred Harder

Halfway through a long loop, the riders still making good decisions are usually the ones who sorted their fuelling before they needed it. On NZ trails, that matters as much for handling as it does for speed. Low energy shows up in sloppy line choice, rushed braking, and poor calls on technical features.

Energy gels NZ riders use are a normal part of the kit now because they solve a real problem. They are small, easy to carry, and practical when a ride is too rough, too cold, or too stop-start for bars and real food to work well. As noted earlier, this is an established category here, not a fringe one, and local supply makes it far easier to build a system you can depend on.

The simple rules still hold:

• Fuel before the slump starts.
• Take gels with water so they sit better and absorb properly.
• Choose products that suit the trail, the weather, and your stomach.
• Test your plan on ordinary rides, not just event day.
• Buy local if you want fewer delays, fewer surprises, and easier top-ups.

That last point is more important than plenty of riders realise. Importing can look cheaper until freight drags on, stock changes without warning, or a product arrives that is not ideal for the kind of riding you do here. A Nelson winter ride in cold bush conditions is a different fuelling job from a dry summer mission on open trails, and local bike and nutrition shops tend to understand that straight away.

Get the basics right and the whole ride improves. You keep more punch for late climbs, stay clearer through technical sections, and finish the day feeling like you rode properly instead of just surviving the last hour.
