Whats the most effective way to use the data from a Garmin Edge 530 and power meter to create a training plan thats tailored to an individuals specific strengths, weaknesses, and goals, and are there any specific metrics or data points that should be prioritized when setting up the plan? Should the focus be on metrics like Functional Threshold Power, or is it more important to look at things like Training Stress Score and Chronic Training Load? How do you balance the need for structure and consistency in a training plan with the need for flexibility and adaptability, and what role do tools like Training Peaks and Strava play in the process? Are there any specific training plan templates or models that are well-suited for use with a Garmin Edge 530 and power meter, or is it better to start from scratch and build a custom plan?
