Hard to explain, but what running distance world record when averaged per lap is just faster than your PR in 400m?
For example:
Kenenisa Bekele’s 10,000m WR lap average is 63.1 seconds and my fastest 400 is 63.8 so his average lap time is faster than my one lap PR. ya i know I’m slow I’m probably only faster than the average person.
I could imagine competitive distance runners would start to struggle at maybe Hicham El Guerrouj’s 2000m WR average pace of 56.96 seconds.
I wanna know from other people what long distance WR is faster than your 400 PR when averaged per lap? Women’s WR can be used, I just used men as an example
