LeCoach can add heart rate targets to your workouts automatically, next to the power or pace targets.
Enable it
Go to Settings → Workout Settings.
Enable Secondary HR targets.
Your LTHR and Max HR must be set (Settings → Sports Settings) — LeCoach maps each power/pace step to the matching %LTHR using your zones. Steps then read like -5m 92% FTP 88% LTHR. This works for cycling and running.
When you enable it, LeCoach offers to add HR targets to your existing future workouts as well; new workouts get them automatically. Turning it off stops adding them to new workouts.
Why use it
Riding without a power meter: follow the HR reference instead — see Training with heart rate.
Devices show HR alongside power/pace, useful for endurance rides where drift matters.
A note on HR lag
Heart rate reacts slowly. For short intervals (under ~3 minutes) the HR target is a sanity check, not something to chase — power and feel lead, HR confirms.
