While the potential team scrambles to even get registration open, challenge #1 is already out. See below.

To add to it:

Post in the usual event page.
Challenge has no due date, but if it’s done before October you get a bonus point.
Completion earns you two points if you do both the burpees and squats. One otherwise.
As usual, those who haven’t registered (that’s everyone right now) are eligible to complete challenges and earn points. Only when they register are the points actually active and able to be used for unlocking perks.
