We saw some great races in Tokyo, but there are a few more we still need to see, including Sha'Carri Richardson vs the Jamaicans at 100. Karsten Warholm vs. Rai Benjamin vs. Steven Gardiner at 400, Sydney McLaughlin, Dalilah Muhammad, and Athing Mu vs Shaunae Miller-Uibo at 400; and a showdown between the men's Olympic 1500, 5k, and 10k champs - Ingebrigtsen, Cheptegei and Barega - at 5000.
