Race with my master in Swimming class

I had an absolutely wonderful day yesterday. Good day at school and finished my assignments as soon as i came back. In the evening i went for my swimming class. My master made me do all the strokes multiple times. I did freestyle, breast stroke, butterfly strokes, whip kicks. He also made us do these styles just using hand and no kick. This is to strengthen my upper body. I could definitely feel the difference as i know i am feeling much stronger now doing my push ups and sit ups everyday. Finally we had freestyle race - 50 mts and i won it. My master challenged me to a 25 mt race. He gave me a 4 sec head start since i am very young and we raced. All parents and students cheered me. I won touching the wall a stroke earlier than my master. He called me the "Beast" as i was very fast even tho i am small and young. I felt good and need to make sure i keep working on my push ups and situps to get more stronger.
