If I can run 5 miles confortably will i be ready to tryout for track and field? - canada track field records

I wrote a post on the training boring .. (5 miles easy running) ... I wonder, im going to Run in the 9th Class (long distance) in Canada and if you learn to comfortably run 5 miles ... I'm ready to run easy to follow ... When the season begins, I'll be able to perform better or more effective than others? Either I'll slow down?
