What are the positions in track?

First off, to clarify they aren't called positions. They are all different events, so the results from shot put are separate from the results from pole vault, and so on. I don't know if you're in the USA or Canada, wherever you are has slightly different events (like for example, USA has the mile run and Canada has the 1500m run). But if you're really fast, I would say go out for sprints and hurdles. Maybe you can also try long/triple jump and high jump. Just see what you're best at.
