Why This Update Matters

More Dependable Race and Coaching Data

Race events and Garmin Run Coach are central to how many Forerunner 955 users plan structured training. Version 28.05 makes that information more consistent between the watch and Garmin Connect Mobile.

Better Activity Save and Upload Reliability

The upload fix is useful for every user, while the course-navigation save crash fix is especially relevant for runners and triathletes who navigate courses during activities.

Map and Accessory Polish

China OSM map fixes and Schwinn pairing improvements are targeted, but they remove friction for users who rely on those specific features.
