YOUR BODY DOESN’T KNOW THE DISTANCE.
It only knows the demand.
Your body doesn’t know if you’re training for:
• A 5K
• HYROX
• CrossFit
• A Half Marathon
What it does know is:
• Intensity
• Duration
• Oxygen demand
• Energy cost
That’s why great endurance training isn’t built around race names.
It’s built around physiology.
Train the system.
Improve the system.
Then apply that system to the event.
The athlete who understands the demand will always train smarter than the athlete who only understands the distance.
