Missing Running Lactate Threshold Data in Garmin Connect Web

Lactate Threshold data is missing in Garmin Connect Web.  Specifically the '4 Week' and '12 Week' tabs.  '1 Year' appears but appears cut off at the bottom of the screen in both Chrome and Firefox web browsers.

This data --IS-- available on the Android Garmin Connect app.

  • I see the LT report normally, as always, including the 4w, 12w, and 1y, with no parts cut off. Could you post a screenshot demonstrating how it looks like on your end? Are you using a PC, Mac, Unix, tablet, or a phone?

  • My 4 Week and 12 Weeks tabs also show no data, though the 1 Year tab seems to show all data correctly (Win 11/ Chrome), though there is a large empty space between the tabs and the graph.

  • PC with Chrome (latest) and Firefox (latest).  Garmin Connect Android has no issues.

    Yeah, I'm getting back into running (hopefully competively after a 10 year break).  No shade on the LT scores!

  • Strange, mine looks normally in Chrome, Edge, and Opera. No empty space:

  • Cleared cache in Chrome on WIn 11 - same results. 

    Opened in Chrome on Android tablet - same results

    Opened in Edge on Win 11 - same results. 

    That points to it not being a browser problem. 



  • I have had the exact same issue for at least several days now. The 4-week and 12-week graphs are missing. The 1-year graph is down below and is viewable if I scroll.
    Windows 10 Version 22H2 (OS Build 19045.5796)
    I have tried:
    Firefox 138.0.1 (64-bit)
    Chrome Version 136.0.7103.49 (64-bit)
    Microsoft Edge Version 136.0.3240.50 (64-bit)

    The data exists and is viewable for me in the Garmin Connect Android app.

  • I notice the design of your tabs look different from druidh's and Sean C's. I don't know if that is a clue. It is not browser specific because the design looks the same on Firefox, Chrome and Edge for me.

  • Same here. Not showing 4 and 12 week graphs and the Year graph is pushed down the screen leaving a blank gap. Using Safari on both a MacBook and iPad, it’s the same on both…..

  • As of today (21st May), the 4 week and 12 week charts are now showing the LTHR graphs again and there's no large gap in the 1-year graph.
