Every runner dreams of pushing their limits and conquering longer distances. But how do you build the stamina to run that marathon or conquer that next challenging trail? Enter Long Slow Distance (LSD) training, a cornerstone practice for distance runners seeking to unlock their true endurance potential.

LSD training involves running at a comfortable, conversational pace for extended periods. Don’t be fooled by the “slow” – this method is anything but easy. By consistently challenging your body with manageable distances at a lower intensity, LSD training unleashes a cascade of physiological adaptations that transform you into a more efficient running machine.

Here’s how LSD training empowers your running journey:

• Boosting Your Oxygen Delivery System: Imagine a robust network of tiny highways delivering oxygen directly to your muscles. LSD training expands your capillary network, increasing the surface area for oxygen exchange. This translates to more power reaching your muscles, enabling you to run farther with less fatigue.
• Power Up Your Cells: Mitochondria, the “powerhouses” within your cells, are responsible for energy production. LSD training increases the number and efficiency of mitochondria, allowing your body to generate more energy from oxygen, further enhancing your endurance.
• Fat as Fuel: Long, slow runs prime your body to utilize fat as its primary fuel source. This not only conserves precious glycogen stores (your body’s readily available energy) but also allows you to run longer distances before hitting the wall.
• Fueling Your Long Runs: Think of glycogen as your body’s energy reserves. LSD training increases your glycogen storage capacity, ensuring you have ample energy reserves to tackle those longer runs.

By incorporating LSD training into your routine, you’ll witness a remarkable transformation in your running. You’ll be able to run farther, feel stronger, and recover faster, propelling you towards achieving your distance running goals.

So, lace up your shoes, embrace the slow and steady approach, and unlock the hidden depths of your running potential with LSD training.
