Great job Justine and Sharon! This is a great way to challenge each other to be active. I can't wait for the next one!

I would be good with all of the challenges, including another step challenge. I also think it would be cool to have multiple challenges running simultaneously as well. For instance, the weight loss challenge could run for 6-8 weeks, while we have other challenges (step, hydration, etc.) that each last a week within that timeframe.
