When it comes to endurance training and racing, nutrition isn’t just about gels. While energy gels are convenient and provide fast carbohydrates, carbohydrate drink mixes with electrolytes are often even more important for maintaining performance over long sessions.
Why Drink Mixes Matter
During endurance exercise, your body loses:
-
Carbohydrates: The primary fuel for muscles and brain
-
Fluids: Through sweat, causing dehydration if not replaced
-
Electrolytes: Sodium, potassium, magnesium, and calcium are lost in sweat and are crucial for muscle function and nerve signalling
While gels provide carbs, they don’t hydrate you. Without fluid replacement, your performance can quickly decline due to dehydration and electrolyte imbalance.
The Benefits of Carb Drink Mixes with Electrolytes
1. Sustained Energy Delivery
Drink mixes provide a steady source of carbohydrates over time. Unlike gels, which give a short burst of energy, carb drinks keep your blood sugar levels stable and delay fatigue during long rides, runs, or triathlons.
2. Hydration and Electrolyte Replacement
Adding electrolytes to your carb drink helps:
-
Maintain fluid balance
-
Prevent cramping and muscle fatigue
-
Support optimal heart and nerve function
3. Gut-Friendly Fueling
When taken in the right concentrations, carb-electrolyte drinks are gentle on the stomach. This allows athletes to consume more carbohydrates over longer periods without gastrointestinal discomfort—something gels alone can’t always provide.
4. Flexible Fueling Strategy
-
Before Training/Race: Carb drinks can top up glycogen stores
-
During Training/Race: Provide both hydration and fuel
-
Post-Training/Race: Help kickstart recovery when combined with protein
How Carb Drinks Complement Gels
Gels are excellent for quick bursts of energy, especially during high-intensity efforts or when you need to top up mid-race. However, relying solely on gels without fluids can:
-
Increase risk of dehydration
-
Cause digestive issues
-
Limit your ability to sustain carbohydrate intake
By combining gels with carb-electrolyte drinks, you can:
-
Maximize carbohydrate intake per hour
-
Maintain hydration
-
Reduce the risk of GI distress
-
Support consistent muscle function
Recommended Use
-
Long training sessions (>90 minutes): Start sipping carb-electrolyte drinks early and continue at regular intervals
-
High-intensity sessions: Use gels strategically for extra energy spikes, complemented by drink mixes for hydration and steady carbs
-
Race day: Plan a fueling strategy that balances gels and drink mix intake based on sweat rate, intensity, and duration

Final Thoughts
Endurance success isn’t just about consuming carbs—it’s about how you combine hydration and fueling. Carb drink mixes with electrolytes ensure you stay hydrated, fuel your muscles, and maintain performance over long sessions. While gels are useful for quick bursts, a proper drink mix forms the foundation of any effective fueling strategy.
