To run 1:29 you need sub 30 200m speed and Tuohy usually kicks in the 31, 32 second range. Of course the races are longer but still. To me thats an 800m runner pace. So, I guess not really sure about this one.
I do think that Wiley's times show she is in at least 4:30 shape if not faster. She also front ran all these races with no competition except in the 1k.
