Sharing a Watch

My wife and I want to share a Garmin watch. I know that we'd be forced to use one Garmin account, and that's fine. I like to track all my runs via Garmin Connect, and she writes down all her runs by hand with notes.

The question is does the watch itself learn from individual runs, and adjust pace, cadence, etc. to each individual? In other words, lets say I had my watch for a year and then my wife started using it. Will the watch apply my stride/cadence/pace to her runs such that her stats and instance pace are "off"? Or is each run done on a watch completely separate from one another?

As a note, we're not concerned about things like VO2 max and other stats. Just what the watch is showing during a run.

Thanks.
  • What the watch learns is the user's stride for use when GPS is not available, like indoor runs. For GPS runs it should make no difference.

    from my experience the only real thing would be wrong numbers on all the Trainingeffect fields etc.
    The watch knows what you normally do, what your Heartbeat is for a given pace and so on.

    If you only want to count the Distance, time and speed it shouldnt be much a problem.

    If you plan to use all the Garmin Connect features I dont think you get accurate numbers


  • In terms of physiological feedback provided by the Firstbeat analytics engine built into your Garmin FR935, sharing the watch with someone else is going to put pretty much everything that benefits from personalization out of whack. Not interested in VO2max? Fair enough - but here's a quick overview of some of the other 'showing during a run metrics' that will be impacted. They won't be accurate for either user.
    • Performance condition - how your current run stacks up to your norm
    • Aerobic Training Effect - degree to which your run stimulated development of aerobic performance capacity
    • Anaerobic Training Effect - degree to which your run stimulated development of aerobic performance capacity
    • Calories Burned -
    You'll also render these features completely useless.
    • Training Status
    • Training Load
    • Recovery Time
    Without trying to tell anyone their business, that sounds, to me, like quite a bit to give up for someone who invested in a flagship device, especially considering that Garmin has devices like the vivosport and the FR 35 in the $150ish price range.

    OK, if you're sure that's what you want, and can see some benefit from it.

    OK…

    The question is does the watch itself learn from individual runs, and adjust pace, cadence, etc. to each individual?
    Yes, but only if you save the timed activities.

    Just what the watch is showing during a run.
    Then tell your wife not to save any of the timed activities on the device after completing them, but only copy out by hand what is shown during the run (and can be reviewed once the timer is stopped, without the activity being saved).
  • The distortion of statistics notwithstanding, you can link the watch to 2 different Connect accounts. The way I did it is to link to one account through Express and another through Mobile Connect. There is a definite risk of the wrong activity going to the wrong account if the user isn't careful but it can be done.
