Is it really worth following a structured plan when all the pro cyclists seem to get their endurance through doping, and would a clean rider ever be able to compete at the top level without some sort of banned substance or shady training method in todays racing environment, or is that just a major misconception about professional cycling thats been perpetuated by the media, and what exactly does a structured plan even consist of for a rider looking to improve their road cycling performance in a more grassroots setting, such as participating in local events and charity rides, would it be better to focus on developing a specific skill or attribute, like climbing or sprinting, or should a rider aim to be more of a generalist with a well-rounded set of skills, or would that just lead to being a jack-of-all-trades and master of none, and how much of an impact does nutrition and recovery play in a structured plan, or is that just something thats overemphasized by people selling supplements and training programs.
