It's very complicated. Certain races have the top 3 non qualified Japanese athletes that run sub 2:11, and the next 3 if they run sub 2:10, for women 2:28 and 2:27. This is a qualifier race for men but not for women. But you can still get the 2:28 average for this race.
Wow. They don't mess around in Japan I guess.
If the US had those standards for men, Galen Rupp would be running alone right now, lol.
