Narrative:

I was entering the pattern at ZZZ to land flying a C172. I crossed the runway at 1000ft MSL to enter the right downwind for runway xx which uses right traffic. As I crossed over the runway there was aircraft Y; a DA20; executing a low pass over the runway. I started my turn into the downwind and he started his turn to crosswind and then to downwind. I looked back and he was closer to me then I was comfortable with so I speed up a little bit. Then when I turned final I received a traffic alert saying he was at my six less than one mile. I asked my passenger to watch him and she told me he looked like he was 200 feet from us and looked like he was about to pull up alongside us. I chose to go around rather than risk him landing on top of us. I also chose to execute the go-around because he never acknowledged my position in the pattern during his radio calls he acknowledged the two aircraft in front of me.
