For the last few months when I go for a run it seems to add on extra distance right from the start of the run so the voice cues for split times are worthless and then at the end of the run the distance is inaccurate but once I get home and it syncs it usually fixes itself although the miles at the top of the map still show up wrong, yet in the weekly exercise bit, it is correct. I have restarted the Fitbit several times but it doesn't seem to make any difference. It's got to the stage now that I'm thinking I'll have to get a new device as I want to know when I am running how far I've gone, not wait until I get home and sync it. And it can't be poor GPS as it is adding miles at the very start.
