Search Results: talking to him outside of class

There is a guy in one of my classes (I'm in college) and I think he is attractive. I see him in class twice a week and we occasionally make eye contact. We both always go to the gym after class but have never talked to each other. Today after class on the walk to the gym (we have never walked together before), he walked past me as we walked out of class, but then turned around and asked me if I was still going to run on the treadmill (I always run on the treadmill on the days we see each other in the gym) even though it was so nice outside. We then talked the whole way to the gym. We made eye contact and laughed with each other. When talking, I told him I almost tripped on the indoor track last time and he said that he has tripped up there before. (idk if sharing an embarrassing fact is relevant at all). What does this mean? Is he interested? Help? 
