Heart rate, and every workout you kept.

You most likely landed here from an answer that came up short. On the free plan your assistant reads the last 30 days and no heart rate at all — it tells you so, in the same breath. Pro hands back both.

Your workouts keep syncing either way. Nothing is deleted, nothing is re-uploaded: the day you subscribe, the next answer is complete.

The same question, twice

Free

How hard did I actually go on Sunday's climb?

I can see the climb — 41 minutes, 612 m of ascent — but your heart rate is withheld on the free plan, so I can't tell you how hard it was. That's the one number this question turns on.

Pro

How hard did I actually go on Sunday's climb?

healthsync · get_workout_series 2,408 samples

You held 171 bpm for the last 12 minutes, 94% of your max, after sitting at 158 for the first half. That's a hard effort finished harder — and it's the third time this year you've done that on this climb.

What Pro adds

Every heart rate series: Beat by beat, plus variability and one-minute recovery. The free plan withholds all three, averages included.
Your whole history: Not the last 30 days. Every workout you have ever synced, as far back as your watch goes.
Nothing else changes: Same app, same sync, same assistants. Pro only widens what they are allowed to read back.
