Create a Friend Challenge
To create and join fitness challenges, tap the Menu icon (three horizontal lines) in the top left of the Start Workout screen, then select "Challenges." You can toggle between "My Challenges" (challenges you are currently participating in) and "New Challenges" (sponsored challenges that are currently active, but that you have not joined). You can also tap the "+" icon in the bottom right corner to create your own challenge with friends!
After tapping the + icon, fill in the requested fields to create your challenge. Lastly, invite your friends to participate! Tap the "Friends" section, then tap the "+" icon next to the friends you wish to invite, then tap "Done." When you are ready, tap "Start Challenge." Your invited friends will receive your request and can either accept/decline the invitation to participate. Note that if your profile is set to private, you will not be able to create a friend challenge or be invited by a friend to participate.
Viewing Challenge Leaderboards
Once your challenge has been created and at least 1 participant has accepted, you can view your challenge's leaderboard. To do so, open the MapMy app > Menu tab > Challenges > select "My Challenges" from the top > then select the challenge of interest.
Leaving a Friend Challenge
To leave a friend challenge you have already joined, tap the "Rules" tab of the Friend Challenge > tap "Leave Challenge." If you are the challenge's creator, you must tap "End Challenge," which will end the challenge for all participants.
