Practice for a athletic meet

Today, I have no class. I want to rest whole day, but I shouldn't. I have to go a playground at 3 pm. In there, department of English education have practice for a athletic meet. I participate in <20 legs, 21 persons> game and game. Practicing it was not easy, because everyone should have to be like one. Pracing takes for 3hours. It was so long that most of us get exhausted. Now, I want to sleep.
