I've done this on my Edge 520 with no issues for at least a year now.
Yes, I can do that. As I mentioned in the original post, though, we have quite a lot of tree cover here and I find the speed a bit erratic when using just GPS. This is more noticeable when mountain biking, but at this time of year, with lots of leaf cover, it affects the speed reading on the road bike too. I know it doesn't matter greatly but I'd rather have an accurate speed if I'm recording everything.
