Check out my first activity.
HR drops to 63. The strap is the Garmin HRM-RUN. Less than a year old. Works fine on other garmin devices.
What's going on?

    so are they going to fix it or just say its not compatible. Not much good when your doing a Triathlon and want the 520 on the bike and the HRM-RUN for run stats....


    You can get that...with the new Tri specific HRM. Which will cost you around $90 :) Really curious to know what ships with the HRM 520 Bundle.
  • Can you copy the body of the email so we can see what they said? Thanks!


    It's in Danish so I don't think that you get much from it.
    But loosely translated it says "The properly cause is that the HRM-RUN is not compatible with the Garmin Edge 520, please try a non HRM-RUN belt to check if you experience the same issue".

    No identification whatsoever if a fix is coming.

    And I agree with you that this is a serious problem, I'm using this in conjunction with duathlon and I don't want to stop and change belt in transition.
  • A fix is needed asap... I have a century ride next weekend and don't want to have to worry about this... The he issue causes a pretty significant variance in calories expendeture... I've also found that my vo2 Max estimation has gone way down since I started experiencing the hr drop... From 55 to 43.

    I got an email from Garmin support today and they kinda confirmed that the HRM-RUN is incompatible with the Garmin Edge 520 and asked me to try a normal HRM belt instead.

    So I will try that on the training ride tomorrow.

    Best regards

    That's quite remarkable given the fact that the bundle according to Garmins own description, ships with "Premium heart rate monitor" which as I understand, is the HRM-Run Edition... Edit: I see that it's a difference between the HRM-Run and Premium HRM straps.

    I had my first ride With the 520 yesterday with a HRM-Run strap and I also noticed many "low drops" not observed on my FR920xt. I have a old strap (from FR610) and will try this on my next ride.

    As a side note, everything except HRM and a couple of other features (se next sentence) worked as expected and Strava segments where shown in real-time with real-time information during a segment. The HR zones was not updated on the device after several synchs trough Connect and I had to adjust them manually on the devide after the ride (will do a new ride today) - not the most intuitive part of the UI on the device... And Strava segments are not visible in my Connect app (iPhone 5) - only in the Connect Web Application after re-establishing the Strava Access to Connect.

    I Guess a SW update or two will arrive soon.

    I will update this thread with information utilizing the old HRM strap. Edit: Did not find the old HRM strap today, but the same "low drops" to 63 bmp, was recorded today both live on the device and in the FIT-file. Will try to locate the old HRM strap ASAP.

    Actually there are two kinds of HRM straps, a HRM-RUN normally shipped with a running or triathlon watch and a Premium(the old or original strap) one shipped with cycling computers.

    After my training ride today, I can confirm that the HRM-RUN is not compatible with the 520. I rode with the normal strap shipped with the 520 today and it worked completely as expected and I didn't even have a fallout of the ANT sensors like the previous ride.

    So Garmin have to come up with a FW fix for this issue soon 😎

    See posts above yours. 920 ships with HRM run. Currently not compatible with the 520.
  • Well - I have this belt with the HRM-run module on it (came with my 920XT). Click on the "Compatible Devices" and scroll down. Edge 520 is there.

    I'd guess we can expect a firmware update quite soon...

    This is quite interessting - on the german Garmin webiste i checked the compatible devices for the HRM-Run (https://buy.garmin.com/de-DE/DE/zubehor-auswahl/fitness-sensoren/hrm-run-herzfrequenz-brustgurt-run-/prod133715.html) which costs 99€ (!!!). The belt is NOT compatible with the Edge 520.

    BUT if you take a look on the 30€ cheaper so called "premium belt" (https://buy.garmin.com/de-DE/DE/prod15490.html) - the compatible devices list displays the Edge 520.

    I posted these facts on the german Garmin D facebook account and wait for a response because i only have the HRM-Run belt in use with my 920XT
