I consider my training a jagged climb. The goal isn't to peak once per season, where that's the best I can possibly get. The goal is to be @ A peak for each event I want to perform my best at.
I definitely believe that periodization works, whether you want it to or not. Over time we're bound to have "micro" and "macro" periods. Two steps forward, one step back and all.
