Indeed, it's absolutely mind blowing.

Top marathon runners average faster than five minute miles. That's sickeningly fast.

Back in high school my fastest single 1600m (a mile is 1609m, but one lap on a track is 400m) time was around a 5:15, and my fastest 800m was 2:27.

These elite marathon runners basically took my fastest 800m pace and repeated it 50 times.

Insane.

For comparison in the other direction the world record 800m is David Rudisha 1:40.91 (2012). That's also ridiculous.

A bit faster actually. Just under 4:35 pace!
