Controversial take here but I think the women 3k outdoor WR is literally the hardest one in the books, men or women. I know what the points say, but look at the all time lists. Literally no-one outside of a Chinese runner has run within 10 seconds of 8:06 outdoors. I mean, 8:06? mind boggling. It's just unbelievably fast.
Anyway, statgangsta (https://timescalculator.appspot.com) says Faith can run around 8:06 low with PR's of 3:49.11 and 14:05.20, and with PR's like that the 3k should literally be the perfect distance for her, but I'm honestly not sure she can get it.
