Just a super quick post to provide a tiny bit of context on an issue some (but not all) folks are seeing where your recorded GPS track is offset by upwards of a hundred meters or more. In general, the pattern of your route is correct, but it may be displaced to one side or the other. However, in many cases by the completion of the workout, it sorts itself out. In other words, it’s mostly a one-time issue.
