Dang it so close. I do have another question. It’s on the watch, the forerunner 935, it’s working great so far and I love all the extra data I get but one thing I can’t figure out. While out on a run my background is white but there are random times when the background is black. I am not sure what that means. It is random, to me so far. I thought maybe it meant I was climbing but when doing a real Hill it was white. I thought maybe it was when I lost signal with gps as some times it is when I am under an overpass, but not always. I still think the lack of gps signal might be it but not sure. I tried googling but have not figured it out yet. Thoughts?
