even with rupp's improvement of the 10k AR, the standard 8 have beaten, which is the Olympic A standard of 27:45, is only 57 seconds back, whereas the women's standard of 31:45, the Olympic A standard, is 1:23 back of the AR. What you have is a dearth of top women trying the 10k and a dearth of opportunities to run one on the track, frankly. But the men have found enough of them.
