Hi everyone,
I’d like to raise awareness about a reproducible issue I’ve encountered with the Forerunner 255 in custom multisport profiles:
Issue (reproducible):
-
When using a custom multisport profile (Run → Bike → Pool Swim), the GPS track from the Run segment is incorrectly assigned to the Swim segment in Garmin Connect.
-
The Run segment itself lacks advanced charts (pace, cadence, elevation, HR zones), showing only basic stats.
-
This happens both when modifying the default Triathlon profile and when creating a new one from scratch.
Key tests performed:
-
Regular Run and standard Triathlon activities function correctly.
-
GPS lock, reset, and creating new profiles do not resolve the problem.
Device info:
-
Forerunner 255, Software version: 24.12, Activity tested: Aug 1, 2025.
I’ve shared this with Garmin Support previously, but they advised using the Ideas form, which is more for feature requests rather than bugs. Posting here in hope that others have experienced this too—and to give it visibility in case Garmin’s development team reviews the forums.
Happy to provide FIT files, screenshots, or recordings if helpful.
Thanks,
