  • Sorry if I understood you wrongly, but stryd is broadcasting with both Bluetooth and ant+. Garmin is supporting all stryd metrics but power. That is exactly what we are asking for. Sorry if I misunderstand you, not an English speaker. 

  • Can confirmg - today''s non serious activity (sport with kids) OHR showed values 160-175. After watches restart values were ok (100-120 bpm). 

  • Got you. I dont use Training Peaks. I use the Stryd plans and use the CIQ app. It works just fine. The only thing that I am missing from the CIQ app, which to me is a big deal, is that you cannot plan on distance. Just time. I asked the Stryd team a couple weeks ago and they said that there was no solution and they were not planing to get one in the close future.

    I'm a long time Stryd user too but because it's not native you have to use their CIQ app for workouts that alert you regarding your zone (in vs out).  But you lose some of the Garmin stuff (like datafields) when you use the Stryd app.

    There are workarounds but it's not nearly as easy to run with power on Garmin like it is with cycling power.

  • No e-bike Profile in Garmin connect is nowadays really a "problem". It looks like some people did oversee one of the biggest trends in cycling in 2020, the other one is Gravel (wich is also not available).

  • I have a basic ANT+ pod (it's Timex, but made by the same company who made the Garmin one), but was hoping they would have come up with something better in the last decade this thing's come out.  And they aren't still making it - try to buy a new one online.  Regardless, it does help, but isn't perfect.  Thanks for the info BTW!  

  • didn't know they dont sell it anymore.
    im also not a native English speaker.
    I know Stryd is broadcasting power via ANT+, but its their own protocol and not an ANT standard. 

  • That's what I wondered?

  • Thanks Garmin crew! Some pretty exciting new features, good that recovery time takes sleep into account, does that mean I should wear the watch sleeping now because I thought the sleep isn't that accurate so won't the recovery time not be so accurate. I would love if you guys took hills into the recovery/performance condition.

  • I would hope full integration would free up a CIQ field having to be used just to get power metrics as we only have 2 to work with in each profile.

  • That’s a good point.
