在她跑完一千米之后,她已经精疲力竭了(英语翻译,用cover)

After covering one kilometres, she was worn out.

After she covered one kilometres ,she was exhausted.

She was exhausted after she covered 1,000 meters' running.

SORRY,什么叫用COVER啊?
我是这样翻的:
She's wearing out after 1000m running.

After she covered 1000 meters,she got tired/exhausted (all over).
