Not saying these times aren't amazing but what's the deal with the 300+meter track? Exactly how is it advantageous? If the turns would be less tight on a 400 meter track indoor or out, then times would be 'faster' with no turns, or does the whip around on smaller track accelerate you ?

"They help runners run AGAINST inertia. When you turn, you change your velocity but you have momentum still going straight. Having a banked track allows you to push more outward to counteract that momentum/inertia, making it easier to turn. Or at least, that's what it seems like to me".

"But it's running. 300 m tracks are faster because there are longer straights and less interruption to momentum. Bankedd tracks where you high and low sap a little of your concentration, have dead spots, and while it may feel super to be running the banks, it's not as fast as a more gentle curve of a 300 track.
And that's why all the times are faster on 300 m tracks than on 200 m banked or otherwise."
