You can be fit and still feel terrible in training.
That's the bit people don't always clock.
A surprising number of runners, riders, HYROX athletes and triathletes are not falling apart because they're undertrained. They're falling apart because they're underfuelled, underhydrated, or winging the sodium side of the equation and hoping for the best. In Singapore and across Southeast Asia, where the heat and humidity can turn a routine session into a slow-cooked sufferfest, those mistakes show up earlier and hit harder. Sweat losses climb, sodium losses vary wildly between athletes, and what felt fine in cooler weather can suddenly stop working.
That's why fuelling is not just "for racers" or "for people doing ultras." It matters for the beginner doing a first 90-minute ride, the HYROX athlete trying not to fade halfway through a hard session, the road runner training before sunrise, and the experienced triathlete trying to hold form deep into a long brick. The good news is that fuelling is one of the most fixable performance problems you can have. Usually, it does not require a personality transplant. Just a better plan.
What Your Body Actually Needs During Training
At its simplest, performance comes down to three things:
- Carbohydrates — your primary fuel
- Fluids — temperature control and circulation
- Electrolytes (especially sodium) — hydration balance
For sessions longer than 60–90 minutes, sports nutrition research consistently supports 30–60g of carbohydrates per hour for moderate-duration efforts, rising toward 90g per hour for longer sessions when the gut is trained and multiple carbohydrate sources are used. In Singapore's heat and humidity, hydration and sodium become even more critical on top of that.
The Low-Down on Powering Up
The guidance across sports nutrition research is broadly consistent: for exercise lasting around 1 to 2.5 hours, athletes benefit from roughly 30–60g of carbohydrate per hour. For longer sessions — especially where the gut has been trained and multiple transportable carbohydrates are used — intake can climb toward 90g per hour. Hydration is equally unglamorous and equally important: start exercise reasonably hydrated, drink early rather than waiting for a full-blown crisis, and tailor fluid and sodium intake to your own sweat losses rather than copying whoever looks fastest in your training group.
Carbs and Common Sense
The simplest way to think about fuelling is this: before training, you want enough carbohydrate on board to actually do the work; during training, you want to drip-feed energy and fluids before the wheels start coming off; after training, you want to replace what you used and set yourself up to recover properly.
For sessions where you've eaten a proper meal 2 to 3 hours beforehand, the pre-session piece can be straightforward: toast with jam, oats with banana, rice with eggs, or anything similarly boring and effective. For very early sessions or harder efforts where a full meal feels like a terrible idea, a smaller carbohydrate top-up 30 to 60 minutes before can work well. This is where specialist sports nutrition earns its keep — it gives you predictable energy without a lot of chewing, guesswork, or digestive drama.
The Fuelling Mistakes That Cost You Performance
Most athletes fall into the same traps.
Starting underfuelled If you begin a session low on energy, you're playing catch-up from the start.
Waiting too long to eat If you only fuel when you feel bad, you've already waited too long.
Ignoring sodium Cramping, dizziness, late-session fade — this is often not a fitness problem. It's a hydration imbalance.
At RDRC, there are a few good ways to handle that pre-session top-up depending on your taste and tolerance. If you want something very clean and minimal, Maurten Gel 100 is still one of the easiest recommendations. If you prefer a different gel texture or want to mix brands to avoid taste fatigue, Saurus makes a solid amino gel range from Japan — look for the AMINO SAURUS GEL — which gives you another well-formulated option to work with. If you're the sort of athlete who would rather chew than squeeze, Bonk Breaker (pictured above) is a useful alternative with more real-food ingredients, while Lecka is especially interesting for Southeast Asian athletes who prefer natural ingredients and familiar regional flavour profiles. RDRC carrying all of these is exactly what makes the store useful: one athlete's perfect gel is another athlete's absolute nope.
Quick Cheat Sheet: Fuelling Before Training
A proper meal 2–3 hours before training does most of the work:
- Oats, toast, rice, banana
- Light protein
- Low fat, low fibre
For early mornings or harder sessions, a smaller carb top-up 30–60 minutes before helps:
- Maurten Gel 100 for clean, fast carbs
- Saurus AMINO SAURUS GEL for smooth, easy intake
- Bonk Breaker chews if you prefer something more chewable
This is especially useful before:
- Early morning runs
- HYROX sessions
- Interval workouts
Once your session moves past the one-hour mark, the conversation changes. This is where athletes make the classic mistake of waiting until they feel weak, dizzy, flat, or irrationally annoyed at a tree. By that point, you are already paying interest on a debt you should not have taken out. For many athletes, a 60- to 90-minute run or ride is where 30–45g of carbohydrate per hour becomes a smart starting point, especially if intensity is moderate to high or the weather is particularly punishing. Push the session beyond 90 minutes, and that number usually needs to climb.
Find Your Sweet Spot
There's no single right product format here — and the internet loves pretending otherwise. For runners, gels tend to be the easiest way to carry precise carbohydrates without fuss. Maurten Gel 100 remains a strong choice for athletes who want simple dosing and a formula that sits well on a working stomach.
Enemoti is a different kind of option — a Japanese mochi rice cake made with palatinose, a slow-release carbohydrate that is absorbed gradually without spiking blood sugar. It's ideal for ultra-pace efforts, long training runs, or any session where you have time to chew and want something that feels like real food rather than a sports product. It's not the right choice at threshold pace, but for endurance efforts it earns its place.
Mag-On (pictured above) is a more distinctive option in the mix — these gels contain magnesium, sodium, and around 120 kcal of energy, which appeals to athletes who want a slightly more loaded formula, particularly those prone to cramping. That said, it still belongs in the "test in training first" category, not the "throw three in a pocket and pray on race day" category.
Keep It Simple and Effective
For cyclists, triathletes, and longer sessions where carrying bottles is practical, drink mix can be a better primary tool — it lets you cover carbohydrate and fluid at the same time. Maurten Drink Mix 320 is the high-carb option when you want to load a bottle properly. Tailwind Nutrition (pictured below) is a smart alternative for athletes who prefer a lighter, all-in-one approach — it tends to appeal to long-course riders, trail runners and anyone who hates overcomplicating bottle maths.
Fuelling During Training: The Timing Framework
For sessions under 60 minutes Water is usually enough. In Singapore's humidity, electrolytes can help even on shorter efforts.
Worth exploring:
For 60–90 minute sessions Start introducing carbohydrates: roughly 30–60g per hour, with fluids and optional sodium support.
Good options:
- Maurten Gel 100
- Enemoti mochi rice cake
- Lecka natural energy bars
- Or if you prefer to drink your calories: Tailwind Nutrition drink mix
For 90+ minute sessions (long runs, rides, bricks) This is where structure matters. You'll typically need 60–90g of carbs per hour, consistent fluids, and sodium support.
Practical fuelling setups:
Precision approach: Maurten Drink Mix 320
Simpler all-in-one approach: Tailwind Nutrition drink mix
Mixed fuel approach: Bonk Breaker or Lecka as solid backup alongside a drink mix
Start With the Basics
If you're newer to sports nutrition, the easiest way to stop overthinking this is to match your fuel to your session. A 45-minute easy run or a basic gym session in tolerable conditions may need nothing more than water and a small carb top-up before you start. A hard 60-minute HYROX session done in Singapore heat is a different animal: you may still not need much during the workout, but you'll often feel better with some carbohydrate on board beforehand and fluids plus sodium handled properly around it. A 90-minute run, ride, or brick is usually where one or two carb servings start making a visible difference. A 2- to 3-hour long session is where you really want a plan rather than a vibe.
Mix It Up
For longer outings, variety is your friend. One reason athletes drift away from a fuelling plan isn't physiology — it's boredom. If every hour tastes like sweet wallpaper paste, compliance drops. That's where a mixed setup from RDRC starts to shine.
You might build a long-run or long-ride system around Maurten Drink Mix 320 in one bottle, add a couple of Lecka gels or Maurten Gel 100s for convenience, and keep Bonk Breaker or an Enemoti mochi rice cake in reserve when you want something chewable and less aggressively "sports product" in feel. That kind of setup works across road runs, trail runs, triathlon bricks, and even long hikes where portability matters just as much as the macro numbers.
Don't Forget Your Electrolytes
The other half of the story — especially in Singapore — is hydration and sodium. Sweat rate and sweat sodium concentration vary significantly from person to person, which is why one athlete can get away with very little while another finishes every session crusted in salt and wondering why their calves are writing resignation letters. Broad fluid guidelines help, but individualised hydration works best: drink enough to limit excessive body weight losses, start early, and adjust based on conditions and how salty a sweater you are.
That's where electrolyte options become more than a nice add-on. For day-to-day training and heavier sweating, SaltStick (pictured above) is a reliable recommendation — it gives athletes a direct electrolyte tool when plain water isn't cutting it. Tailwind Nutrition also earns a place here because it pulls double-duty as fuel and hydration in one bottle, which is handy when you want fewer moving parts.
Hydration and Sodium in Singapore Conditions
This is where many athletes underperform.
Sweat rate and sodium loss vary widely. Some athletes lose very little; others lose a lot.
You likely need a more intentional sodium strategy if you:
- Sweat heavily
- See salt stains on your clothing after sessions
- Cramp late in training or races
- Feel depleted despite fuelling consistently
Electrolyte options:
Managing Cramping Without Guesswork
Cramping doesn't have one single cause. Fatigue, pacing, conditioning, fluid balance, and sodium losses can all be involved — which means no product deserves to be treated as a magic anti-cramp amulet. But if you know you cramp regularly in hot, long, or high-intensity sessions, targeted products can still have a place within a broader strategy.
CrampFix (pictured above) is stocked at RDRC specifically as a portable cramp-relief option — its shots are designed for athletes to prevent and relieve muscle cramps and tightness during exercise. Used sensibly, it makes sense as a backup tool for cramp-prone athletes in long rides, races, open-water swims, and hot long runs. Just don't let it distract from the bigger picture: if you're chronically underfuelling, underdrinking, or overracing your fitness, no tiny shot is going to do all the heavy lifting for you.
Post-Training Recovery
After training, recovery does not need to be elaborate — but it does need to happen. The broad playbook is carbohydrate to restore glycogen, protein to support repair, and fluids plus sodium when sweat losses have been meaningful. That can be a normal meal if you're heading straight to one, or a quicker stopgap if you need something immediately.
Barebells fits neatly here as a convenient recovery-adjacent option when life is messy and you need something portable before a proper meal. The sports science literature supports the value of post-exercise carbohydrate and protein intake for recovery — in plain English, eating something useful after hard training is a better move than wandering around for three hours pretending coffee counts as rehab.
At RDRC, we know fuelling is personal, conditions matter, and the smartest setup depends on your sport, session length, intensity, stomach tolerance, and sweat profile. A beginner building toward a first 10K might start with Maurten gels, SaltStick FastChews, and a straightforward hydration routine. A rider heading out for a long weekend spin might lean on Tailwind Nutrition plus an Enemoti mochi rice cake and a bag of Bonk Breaker. A marathoner or long-course triathlete might prefer the more precise combination of Maurten Drink Mix 320, Maurten Gel 100, and backup sodium from SaltStick. The point is not that one path is superior. The point is that RDRC has the range and the specialist knowledge to help you find the one that works for you specifically.

The Bottom Line
If you're bonking, cramping, fading, or recovering badly, grit is not always the missing ingredient. Sometimes the answer is less romantic: more carbohydrate, earlier hydration, smarter sodium, and products that actually fit the session you're doing in the climate you live in. That's exactly where a specialist retailer like Red Dot Running Company excels — not just selling you fuel, but helping you fuel with a bit more precision and a lot less nonsense.
