I have been in an ongoing conversation with a Garmin agent for over a month, and haven't yet gotten a definitive answer on this issue:
I have had a Garmin FootPod (the SDM4 - Garmin Model #010-11092-00 since 2008, and have been using it for treadmill pace and distance data ever since. I have used it with a Forerunner 305 (2008-2010), a Forerunner 310XT (2010-2021), a Fēnix 6S Pro (2021 - 2024), a Fēnix 6S Pro Sapphire (2024-2026), and a Fēnix 7X Pro Sapphire Solar (since December 2025).
Since switching from the Fēnix 6S Pro Sapphire, to the Fēnix 7X Pro Sapphire Solar, Garmin Connect has stopped automatically detecting new Running PRs.
My most recent auto detected PR was a 10K PR in September 2025 during this treadmill activity on my home treadmill. It was recorded using the Fēnix 6S Pro Sapphire, the Garmin FootPod transmitting pace/distance, and a HRM Pro Plus transmitting HR and running dynamics. Here is the activity: https://connect.garmin.com/app/activity/20250192935
In February 2026, I recorded a run on the same treadmill with the Fēnix 7X Pro Sapphire Solar, the Garmin FootPod transmitting pace/distance, and the HRM Pro Plus transmitting HR and running dynamics. Here is that activity: https://connect.garmin.com/app/activity/21951970251
When I saved the September run, Garmin Connect automatically detected that I had set a 10k PR of 59:37 at an average pace of 9:37/mile. I accepted the PR.
When I saved the February run, Garmin Connect did not detect a new PR, despite me having achieved a new 10k PR of 57:36 with an average pace of 9:16/mile during that run. I manually set the PR, and contacted Garmin Customer Service to see if they could help figure out the issue. Both the agent I spoke with and technical staff that he elevated the ticket to reported back that it should have counted as a PR and been detected automatically in Garmin Connect when I saved the activity. The agent asked me to keep in touch with him via email if the problem persisted.
On April 8, I set both a Half Marathon and 10k PR during a long run on the same treadmill with the Fēnix 7X Pro Sapphire Solar, the Garmin FootPod transmitting pace/distance, and a HRM Pro Plus transmitting HR and running dynamics. Again, Garmin Connect did not detect the new PRs when I saved the activity. Here is that activity: https://connect.garmin.com/modern/activity/22459352892 Again, I manually extracted the PRs and set them both manually.
I emailed the agent with the activity links and described the issue again. He replied a bit later that some of the people he talked to at Garmin suspect that the FootPod may have been removed from the acceptable devices that can contribute to automatically detected PRs in Garmin Connect, but none of them could confirm that. They were basing this speculation off of the fact that the Garmin Support Page for " What Criteria Determines a Personal Record in Garmin Connect?" has been recently updated.
It used to say as recently as February 2026:
- Indoor and outdoor activities can qualify for PRs as long as the Garmin device is recording distance, using the watch's internal sensors in the case of a treadmill run.
It now says:
-
Indoor and outdoor activities can qualify for PRs as long as the Garmin device is recording distance. If you are recording an indoor run, distance must be recorded through either the watch or a compatible HRM.
When it said, "using the watch's internal sensors," it still obviously recorded PRs where the data recorded by the watch came from external sensors like the FootPod or PR, because that is where all of my older treadmill PRs came from.
I have treadmill PRs in Garmin Connect dating back to February 2024, and all of them were recorded with the pace/distance data coming from the Garmin FootPod to either the Fēnix 6 S Pro or the Fēnix 6S Pro Sapphire, and they all autodetected from activities exceeding the distance of the PR in Garmin Connect. It wasn't until I started using the Fēnix &X Pro Sapphire Solar that my PRs stopped auto detecting in Garmin Connect, requiring me to manually extract the PR from a longer workout and add it as a PR manually.
This has been absolutely most incredibly frustrating mystery, and both the Garmin agent and I are baffled by.
Anyone here have any answers?
