The 400m is not lost to lactate.
It is not lost to pain.
And it is not lost to courage.

It is lost when the nervous system withdraws permission.

In this episode of The Neural Arena, the 400m is examined at nervous-system level — not through myths of suffering, but through neural decision-making under extreme threat.

This episode explains:

• Why the famous 250–320m “collapse” is neurological, not metabolic

• How the nervous system inserts protective braking before muscles fail

• Why athletes feel strong but suddenly cannot express speed

• Why strength endurance and pain tolerance do not solve the problem

• How rhythm, posture, and speed are regulated as a single neural system

This is not mindset.
This is not motivation.
This is neural permission, protective withdrawal, and rhythm collapse under maximal velocity.

Once you understand where the 400m is actually decided,
you will never explain the race the same way again.
