It is actually a conveyor belt like you see in airports. The track surface itself is perfectly clear like glass and the markings are underneath it so when the track moves the marking do not. Pretty ingenious design by Japanese engineers.
We all laugh but this is what track has become. Undetectable PEDs, shoes that significantly delay fatigue, and now tracks that do the same. I don’t have the energy or interest but I bet more OR fell in Tokyo than in any other Olympics. Things will flatten out until the next technology comes along but, in reality, no one is really running any faster that they were 30 years ago.
