If you have run a world major or hard to get into race 5 times in a 7 year period, you should have to wait another three years before running it again. Let others have a chance to have the experience.
Boston Marathon should be a separate level in the world majors since it is so hard to get into. Allow Sydney as a WM (continue to keep the six star program) and put Boston in its own category, an elite category. (I will never qualify so I have zero skin in the game.)
Baby strollers do not belong in races.
Stopping the time is ridiculous especially when most smartwatches have elapsed time and moving time data. Seems like extra work for very little reward.
