The Cycling Power Zones analysis, found on the Progress tab, provides a detailed breakdown of how your training time is distributed across different power output levels. This feature helps you visualize your training intensity, track how it evolves over time, and ensure your efforts align with your specific cycling goals, such as building endurance or increasing peak power.
When you first open the Cycling Power Zones screen, you'll see a 4-week overview. This section visualizes your recent training trends and provides a summary of your intensity distribution.

Scroll down to view a longer-term analysis of your training. This perspective is useful for identifying seasonal trends and tracking your development over an extended period.

Use the long-term overview to see if your training is consistent with your goals. For example, during a base-building phase, you should see a higher percentage of time in lower power zones (Zone 1 and 2), while a race-preparation phase should show more time in higher-intensity zones.
The Cycling Power Zones analysis offers a powerful way to understand and manage your training intensity. By providing both short-term (4-week) and long-term (6-month) views of your time spent in each zone, this feature allows you to assess your training distribution, track your progress, and make data-driven adjustments to better achieve your fitness objectives.
