My first run since the software update and gone are PERFORMANCE CONDITION and respiration rate. I can't ascertain whether it was my body or also a glitch in the wrist HR but my HR was WAY lower than it should have been based on my perceived exertion and historical heart rate data doing similar workouts. I also think the GPS was way off I ran around a track in the same lane and it looks like I was running all over the track in different lanes even off the track. Cmon Garmin--it all worked fine before!!
