It's a "how tall is a tree" question. And answer.

Until you start actually competing or at least start doing fast group rides it's difficult to identify strengths or weaknesses, or even what events you might find the most fun. Only then can you start to develop a training strategy.

Crits, road races, TT's, track, and stage races all have different needs.

My advice would be to do some events, do some group rides, and keep a log.

Training is not about hours. It's about what you do with the hours.

Rest when you're tired. This is key.

If you want a bit better handle on things buy an HRM, figure out your zones, and when you're out riding avoid a lot of time on the top and bottom ends of the spectrum. Middle of Z2/3 will give you a nice foundation to work off of.
