Apple is celebrating China’s National Fitness Day with a new Apple Watch Activity challenge.

August 8 was first named National Fitness day in 2009, commemorating the anniversary of the 2008 Beijing Olympics opening.

This challenge is not the first region specific one and in- order to complete the National Fitness Day challenge, users will need to record a workout of half an hour or longer.

“Make August 8 an active day,” Apple notes. “Earn this award by recording any workout of 30 minutes or more on National Fitness Day.”
