Whether you’re preparing for a long run, ride, HYROX session, or upcoming vertical marathon, your performance doesn’t just depend on training—it also depends on how you fuel and hydrate beforehand.
What you eat and drink before and during endurance training can make a difference in how you feel, how long you can sustain your effort, and how well you perform.
Here are 5 common mistakes that could leave you feeling drained before your workout even begins:
1. Starting Training Dehydrated
If you wait until you’re thirsty to hydrate, you may already be behind. Endurance sessions can lead to significant fluid and electrolyte losses through sweat, which can affect how you feel and perform.
This can be especially important when training in Singapore’s heat and humidity.
What to do instead:
Hydrate consistently throughout the day and consider adding electrolytes before longer or more intense sessions.
2. Training on an Empty Tank
Skipping carbohydrates before endurance exercise may leave you feeling sluggish halfway through your workout. Your body relies on carbohydrates as a key source of energy, particularly during longer or higher-intensity efforts.
What to do instead:
Have an easy-to-digest carbohydrate-rich snack 1–2 hours before training.
Examples:
- Banana
- Toast
- Oats
- Energy gels before longer sessions
3. Eating Heavy Meals Before Training
A large or greasy meal might sound like a good way to fuel up, but it can leave you feeling uncomfortable once you start moving. Heavy meals may take longer to digest and can cause bloating or stomach discomfort during endurance exercise.
What to do instead:
Choose lighter, easily digestible meals or snacks before training and race efforts.
Think carbohydrates that provide energy without sitting too heavily in your stomach.
4. Only Drinking Plain Water
During longer training sessions, you’re not just losing water—you’re also losing electrolytes through sweat.
Replacing fluids alone may not always be enough, especially during longer or high-sweat sessions in Singapore’s heat and humidity.
What to do instead:
Include electrolyte support during longer or more intense sessions to help replace electrolytes lost through sweat and support hydration.
5. Waiting Until You’re Exhausted to Fuel
One common mistake is waiting until you already feel tired before taking in energy. By then, your performance may already be starting to drop.
For longer endurance sessions, fueling before you crash can help you maintain your effort for longer.
What to do instead:
Fuel consistently throughout longer endurance sessions instead of waiting until you feel exhausted.
Energy gels are a convenient option for runs, rides, stair climbs, HYROX sessions, and race days, especially when you need quick, easy-to-carry fuel.
Fuel Before You Feel Empty
Endurance performance isn’t just about pushing harder—it’s about giving your body what it needs to keep going.
Stay hydrated, fuel appropriately, and plan your nutrition before you start—not when you’re already running on empty.
Train smart. Fuel well. Go further. 💪
