When setting up a Step Challenge, you will set the number of steps participants should take per day, week, or month in order to complete the goal and earn points.
After you set the step goal, you can set the number of points users will earn for completing that goal (daily, weekly, monthly). You cannot edit the goal or points values of a Step Challenge once the challenge is published.
Once your Goals and Reward points values are set, you will see the Points Summary, which is calculated based on the duration of the challenge and the number of daily goals.
