No power meter? You can still follow every LeCoach workout using heart rate.
Set it up
Set your Threshold HR (LTHR) and Max HR in Settings → Sports Settings (they sync from Intervals.icu if known there).
Enable Secondary HR targets in Settings → Workout Settings (details). Every step now carries a heart rate reference.
If your device should guide by HR primarily, set the target priority accordingly in Intervals.icu — see this article.
Riding by HR well
Endurance and tempo: HR is excellent here — settle into the target range and hold it.
Short hard intervals: HR lags 1–3 minutes, so don't chase the number; go by feel (RPE) and let HR catch up. Your recorded HR still lets LeCoach analyze the session afterwards.
HR drifts with heat, caffeine, fatigue and dehydration — treat targets as ranges.
What about your FTP setting?
Workout structures are still expressed in %FTP internally. If you have any FTP estimate (from a past test, Zwift, or LeCoach's conversation-based estimate), keep it roughly right so intensity classification and load stay sensible. Without power data on your rides, LeCoach scores your execution on heart rate, duration and RPE context instead — logging RPE and feel after hard sessions helps the coach a lot.
Thinking about a power meter?
Ask your coach in chat — it knows your training and can tell you honestly what you'd gain.
