M 400m hurdles is absolutely loaded.
Karsten Warholm and Rai Benjamin are obviously total studs among the best in history in this event
Alison dos Santos is looking so good, he jogged during the heats and might join the sub 47 club
Samba seems to be back to top form.
Hyde is looking good as well
W 100m is looking amazing as well with 6 women under 11, we might have a 10.5X time in the final. Elaine Thompson is ridiculously fit and so is Fraser Pryce ant Talou just throwing a 10.7 during heats was crazy
I am a distance guy but i think these are the two most exciting events in Tokyo.
