I completed a Treadmill Running activity today and the activity saved normally. I noticed on the summary screen that the training effect was missing. Upon syncing with connect, the only row under "Training Effect" was the exercise load. The aerobic/anaerobic rows and the primary benefit row are missing. I've tried deleting and reimporting the activity but it still appears to be missing. I can see the training effect if I use the fitfileviewer but it won't show up on the watch or in connect. Any ways to fix/prevent from happening?
It appears based on another thread this could be related to a chest strap? forums.garmin.com/.../training-effect-data-missing-on-mk3-but-read-on
