I noticed when running a 12km race last year that my Garmin logged it as 13.3km. I have since bought a new phone and Garmin still consistently logs 1km when I'm only at about 850m. This adds up to a big discrepancy when running more than 10km. If I log on Strava without wearing my Lily, my runs are accurate. Has anyone else had this problem? How do I fix it?
