Apple Watch Competitions

I’ve just started using the Apple Watch feature where you can have competitions with friend’s dad try to achieve 600 points a day.

I’m in the last day of a competition and want to start a new one with the same person tomorrow, but I’m guessing that it won’t let me because the previous competition hasn’t finished. But if I wait until tomorrow (Wednesday) to offer it, it won’t actually start until Thursday.

Do we always have to take a day off between competitions?
