No, but my daughter has suggested it. I use an I phone, and it's my understanding that the apple watch has that feature. I don't ride alone in the mountains very often, but it would sure come in handy for that.
Unlike just about everybody I know, I don't ride with a GPS device. I kind of wish I had been when I had my crash. At least, I would know how fast I was going in precisely where I crashed. At this point, I'm gonna have to rely on getting that information from my good Samaritan friend when I finally take he and his wife out to dinner.
