This was an amazing race. To make it a little more amazing, Thompson got her 10.61 running into a -0.6m/s headwind. Flo-jo's 10.49 WR is widely believed to be wind-assisted. I'm was (and still am) a huge fan of hers, RIP, but wind does make a difference. The current crop of 100m runners is super talented, so I expect to see the WR challenged soon.
The Jamaican women sprinters are truly in a golden age. This was a highly predictable sweep of the 100m podium — it's possible Sha'Carri Richardson might have spoiled the Jamaican sweep, but frankly I doubt it — but I don't think many would've predicted the Olympic record would fall in a headwind.
Thompson is 29 and could continue to get faster. She's been a bit injury-prone but has managed to peak at both Rio and Tokyo. Shelly-Ann Fraser-Pryce, amazingly a mom at 34, had the fastest time of the year coming into the Games. Could she run in Paris at age 37? Shericka Jackson's transformation from 400m specialist to short sprinter has been nothing less than stunning. She's only 27 and is one to watch.
The Jamaicans could break the world record in the 4x100 relay, although the reduction of the allowable pool of athletes from 6 to 5 will make it harder, since all 3 of the 100m medalists are doubling in the 200m and at least 2 of them would also have to run the 4x100 heats.
