I use the weekly challenge as a motivator to get out and get more steps in. I am in the 40k challenge, which is appropriate for my distances. For two weeks before this last one, some guy was walking 75k a week and winning (gee, good for him). He cycled out, and this past week I was beaten by one person with 86k steps, and one person with 67k steps. It seems that they throw all newbies into the 40k and let it all sort itself out, but what about those of us who take that challenge (relatively) seriously? It is not possible to win with people walking more than twice that distance competing every single week.
Looking into the Fitbit tracking, I've had enough of a motivational fail for 3 weeks now, might be time to leave Garmin. So discouraged. :(
