I see many people saying how Katelyn Tuohy is the greatest ever, while she is absolutely amazing and a historic talent, she does not measure up to what Mary Cain was, at least not yet.
Katelyn's PR in the 3200m is 9:47 outdoor. Cain's PR in the FULL two mile was 9:38, INDOORS.
Katelyn's mile PR is 4:33 outdoor. Cain's mile PR is 4:24, again INDOORS. The only race in which Katelyn surpassed her was the indoor 5000m where she ran 15:37.
Cain also has the national record in the 800m in 1:59, which Katelyn has run nowhere near. So on the high school level I'd say Katelyn is not equivalent to Mary Cain, although she may be by the time she graduates.
But also, maybe it's just Katelyn is more of a 5000 (or even 10,000) runner while Cain was geared towards 2 mile and less
