Apple is planning a Veterans Day Activity Challenge for Apple Watch owners in the United States on November 11. Participants must complete any workout lasting 11 minutes or more to earn an activity award in the Fitness app.

Workouts can be recorded using Apple’s Workout app or another app that adds workout data to Health. Completing the challenge also unlocks animated stickers for use in Messages.

Apple runs a Veterans Day Activity Challenge each year and often marks the occasion with themed content in apps including the App Store, Apple TV and Books.
