Custom zones

Your zones, your way

Turn on Custom zones in Settings → Zones and alerts to name your five training zones and set where each one begins, in beats per minute or as a percentage of your heart rate reserve or maximum. Your zones then drive everything you look at while training: the colours on the live monitor and the summary graph, the vibration and voice alerts when you change zone, and the time-in-zone breakdown for every session.

Zone 1 can start as low as your resting heart rate, so a walk, a Pilates class or an easy recovery spin shows up in its own zone, and the session is kept even when it scores no zone points.

What stays on the standard scale

Zone points and zone speed are deliberately not affected by custom zones. Both are calculated from a linear scale across your heart rate reserve, which is what makes a score comparable, between one of your sessions and another, and between you and anyone else. If custom boundaries moved the scoring curve, a “200 point week” would mean something different for every person who set it up differently, and every comparison in the app would quietly stop working.

So custom zones change how your effort is shown to you. They don’t change how it’s scored: scoring always starts at 50% of your heart rate reserve, or of your maximum if that is the method you use.

Who it’s for

Anyone training to boundaries they already trust (from a lab test, a coach, or another platform) who wants the app to speak in those terms while keeping a score that still means the same thing everywhere.

Turn the switch off at any time to go back to the standard five zones.
