To mix things up, perhaps a "Mystery Challenge" for 2 or more people could be created.
What this could be, once the challenge has been accepted by the joining players, by a certain time, the mystery challenge would then be revealed. These challenges could be who can get the most steps within a specified time, a certain number of flights, who acquired their water intake each day, food intake, etc. or a combination of these. The duration of the challenge could vary from week to week, from 1 day, or 2 days, or even 5 days long.The possibilities are endless.
A trophy, medal or ribbon should be awarded to the winner as well.
This idea would be fun & exciting because people would never know what to expect. This has the potential to be a game changer.
