A while ago a thread was started on this subject. Would it be possible for someone to break all women's WRs from 800m to marathon? It would presumably have to be a marathoner with 800m speed such as Kipchoge/Bekele/Rupp.
The race would have to go something like this (negative splitting):
3:20 * 21.1 = 1:10:20 HM
3:14 * 11.1 = 32:20 10k pace for 11.1k
3:01 * 7 = 15:05 5k pace for 7k
2:47 * 1.5 = 4:10 1500m split
2:32 * .7 = 700m in 1:47
2:25 * .8 = 1:52 last 800m
Last 800m = 1:52
Last 1500m = 3:49
Last Mile = ~4:07
Last 3k = 7:59
Last 5k = 14:01
Last 10k = 29:06
Last HM = 64:59
Marathon = 2:15:19
