['I still remember my high school days, I was a terrific athlete during that time.', 'What athletics did you participate in?', "The runner's marathon. I felt so proud when I came in second place because I had trained for many months for it!"]
Man i know that feeling. But sounds like you worked hard.
I participated in my high school runners' marathon and came in 2nd place. I felt very proud because I trained hard for it.
