Check short vs long duration changes
Separate sprint, VO2, and threshold windows so you can identify which system is improving or lagging.
How to use Power Curve in weekly decisions
Read changes by duration, then connect them to CP/FTP and zone targets before adjusting workouts.
Validate CP/FTP from curve behavior
If threshold-duration segments flatten, recheck CP/FTP assumptions before forcing higher zone targets.
Adjust only one variable first
When curve and workout quality disagree, adjust intensity or duration first, then review the next key session.
Use curve trends, not one-day spikes
A single peak effort can be noisy. Direction across weeks is more useful for planning decisions.
Is Power Curve the same as Power Duration Curve?
In practice yes. Most athletes use Power Curve as a shorthand for a power-duration best-effort curve.
Should I update zones after every new peak?
No. Use trend consistency and execution quality before changing zones aggressively.
Can runners use Power Curve too?
Yes. Running power users can apply the same duration-based analysis logic as cyclists.
