[Grammar] His legs were tired, his body was tired.

[kadioguy]

In the novel The President's Murderer published by Oxford University Press, it writes:
(on page 1)

The man ran faster. His legs were tired, his body was tired. There were noises in his head, he could not see. The tree were two hundred metres away. He wanted to stop running. He wanted to lie down and sleep.
-----------
Why is there no conjunction between the two sentences?

I.e.
His legs were tired, and his body was tired.
There were noises in his head, and he could not see.

Is it a run-on sentence?

Would you please help me? Thanks!

PS I also posted the same question on this , but all of your answers are unique to me. Hope we can discuss with each other. Thank you.

The tree [STRIKE]were[/STRIKE] was (or trees were) two hundred metres away. He wanted to stop running.

It isn't strictly grammatical. It's likely just a stylistic choice the writer has made. However, in the sentence above, there is a problem. Are you sure you copied it correctly? If so, then perhaps there's an additional mistake in the test with a missing conjunction.

If the mistake is yours, then the writer is likely trying to create the impression or sensation of the stress the runner is experiencing.

I'm sorry. It is my typo. The original sentences is:

The trees were two hundred metres away.
