@Mmiller2827 - My best is a tad over 152,000, second most steps in a day was 145,000. And I've done over 100,000 in a single day a total of 17 times. I'm an Ultrarunner so all except one of those were achieved during super long races, including 4 straight days over 100k during a 200 mile race I did last year. There are most likely other ultrarunners who can do, or have done, more steps in a day but they may not use FitBit so it's hard to say. My FitBit profile shows my best as 145,000, not the 152,000, only because I think their algorythm probably just doesn't account for anyone doing more than 150,000 in a day. Some day I'll see if I can do more than my best but that requires starting right at midnight and going until midnight the following night!
