Endurance is more than just pushing your body through physical activity — it’s about sustaining both physical effort and mental focus over time. Whether you're cycling up steep hills, running a marathon, or staying alert through a long day on the sports field, endurance is about staying strong, both physically and mentally, for the long haul.
Your Body is Like a Vehicle
Before embarking on an endurance event — be it a marathon, cycle race, or long hike — it’s important to ask: Is your body ready for the journey? Just like a car, your body needs to be in top shape before setting off. You wouldn’t drive hundreds of kilometres without checking your tyres, oil, and fuel — so why do the same with your body?
A full medical check-up is a great way to ensure your internal “engine” is ready. At Mopani Pharmacy, we recommend speaking to a healthcare provider for personalised advice before starting any high-intensity training programme.
What Fuels You?
Your body runs on three main energy sources — glycogen, fat, and protein — each with its own role during physical activity.
1. Glycogen – Your Quick-Release Energy
Glycogen comes from carbohydrates and is stored in your muscles and liver. It’s your go-to fuel during high-intensity efforts. However, it’s limited — think of it as a small but powerful tank that can run dry in 1.5 to 2 hours without refuelling.
2. Fat – The Long-Lasting Tank
Fat is your biggest energy reserve. In fact, even lean individuals carry enough fat to fuel dozens of marathons. While it’s slower to access than glycogen, it’s incredibly efficient — providing more than double the energy per gram. Training your body to burn fat effectively is key to lasting longer during endurance events.
3. Protein – The Emergency Tank
Protein isn’t meant to be used as fuel — it’s there to build and repair. When your body starts using protein for energy (like during ultra-endurance races), it means you’re running on empty. This is something you want to avoid, as it can lead to muscle breakdown.
Smart Nutrition for Smart Performance
What you eat — and when — affects which fuel tank your body draws from. Eating lots of sugar right before a session can prevent fat burning by spiking your blood sugar. On the other hand, training on water or balanced nutrition can encourage fat usage and better endurance.

Ready for the Journey?
Endurance is a journey, not a sprint. Make sure your body is well-serviced, well-fueled, and mentally prepared. Because when your body and mind are in sync, there’s no finish line you can’t reach.
