I averaged about 11,000 steps a day. However when I join a challenge, my challenge steps are always really high. I'm averaging about 50- 65,000 steps per day in the challenges. It really upsets the other team members because I'm way out in front, however I'm not that far out I don't know what's going on. Any ideas on why this is happening? I'm using a Garmin vivosmart 4.
