The challenges are a great new feature! Thank you for that. The only issue is the duration. It only has a 'weeks' time option and not an "end date' time option. This should be an easy fix since this is already an option for training programs.
You can't have a "30 day fat burning challenge" without the ability to offer the challenge for 30 days. Even the phrase "30 days" is a fairly established marketing fitness challenge phrase. No one says, 35 day boot camp challenge. Or 28 day calorie burn. It's 30 or 60 or even a 90 day. But 35 days? Not so much.
Thank you
