Let's see how it plays...(not like we have a choice).
It may actually be a better scenario. I know when I am at the women's meet, I won't miss the guys. And when I'm at the men's meet, I won't miss the women. I mean, I will enjoy both competitions.
The fact is, shifting from the men to the women then back to the men and then back to the women is somewhat disjointed. It's like watching a series of downs in football and then watching an inning of baseball.
Many years ago, most track meets were males only. They were good meets - they certainly could be staged in less time. It may well turn out that single gender meets are better spectator events than mixed gender.
I guess we will find out.
