Hi,
I just completed a treadmill run with my Forerunner 945. While running I noticed that I got no pace and distance information but still got GCT, vertical oscillation, etc.
I noticed that my Tacx bike trainer was on and the watch was waiting input from it: when turning the bike's wheel the watch's distance field increased. When I disconnected the trainer (in sensor menu) it all went back to normal.
Any idea why the watch would be getting input from the trainer for a treadmill run activity?
Thanks!
