So classification, I would say is a test that you go through to make sure that you more or less in the same category that makes Para sport a fair sport to participate in. My classification is T54. So I'm a T47. My classification is T37. T54 obviously the the class with less impact. For example I can use also my upper body in the uphill or at the start line. So that helps a lot. I was injured at birth. So when I was being born at the umbilical cord wrapped around my neck and the doctor panicked and he pulled on my head really hard and tore the nerves in my neck in my shoulder and did not tell my parents that he had did so. So I didn't get diagnosed with brachail plexus until I was about six months old.
