My favourite sport (MARCO)

Hello I´m Marco. My favourite sport is Judo. I do it in my gim school. I need a special white combat drees and belt.
I go to Judo two days a week, monday and wednesday, at quarter past four till quarter past five. The class last an hour.
There are fifteen people in my class. I play Judo with Javier. 
My teacher is Javier Blanco. He´s a good teacher and he´s forty nine years old. He has won many competitions.
I´m a good player. I have won many gold medals.
I like playing Judo much. I learn Judo because I can defend myself.
