140 is 70 kilometers. It is ok to run 70 kilometers in one night, and some people can do it. Ordinary people don't need to run that far. On the one hand, it is too heavy for their health. On the other hand, the distance of 70 kilometers needs to be replenished all the way, and ordinary people can't replenish it on the way. Anyway, running 70 kilometers in a row in one night, no matter how fast, is awesome.
