Great run by Chep. Beautiful running form! What a pleasure to watch.
It's odd, though, to see someone break a WR and seem so casual across the finish line. Dude should be exhausted, but no. Kind of like Kipchoge sprinting after his own WR. Makes you wonder if they still had some in the tank and, sadly, if it was a clean performace.
The shoes... Well, supershoes and superfoams are here to stay, so the debate is pointless now. Everyone can see these new spikes are faster, but it is what it is. Time to see some WRs and NRs fall, then it will settle again. Whatever.
What I didn't like, and I think is negative for the sport, are the pacing lights. They are taking away an important variable from racing, just so they can get faster times because that's easier to promote. Instead of trying to get the audience to appreciate the complexity of a beautiful sport, they're just pandering to the lowest common denominator.
