I trained track and field when I was 13, but stopped at 15 due to excessive obligations. However, in the meantime I started karate, and it's really going well, but now I'm considering returning to track and field because I really love it and I have more time now.
The problem is, do I have a chance at becoming good in it? I'm 19 now, and while I was in T&F, my disciplines were the 100m and 200m dash. But I don't have to do the same disciplines. I was thinking switching to the 400m. And karate requires considerably less physical fitness than track and field, so my condition is probably far from perfect.
So, is there a possibility of me getting any good results in track and field after all these years? I don't have any sports injuries or health issues.
