If you fancy a group activity, give your friends a quick shout via Racefully chat (in your Tribe or 1 on 1). Agree on the date, time and who will host the activity.
Go to Schedule in the menu. There you'll see everything you've already got in your schedule. Tap on Schedule an activity to create the invitation.
Give your activity a name, start time, and distance. It's a good idea to include the type of activity in the name. Now you can invite friends from your tribe, Racefully friends, or email contacts.
If you're the host, create the actual group activity right before your agreed start time. Then your friends will be able to see and join your group activity in their activity list.
