It's easy to share Racefully activities inside and outside the app. Even better, the shared activities aren't just a photo and some stats - anyone can take your activity and walk, run, ride or race with it.
In the menu, select My Activities, then scroll or search to find the activity you want to share
Tap the share 
button at the bottom-right of the screen to open the sharing screen
Choose your route map, an image from your photos or camera, or a picture from the Racefully library to go with your activity
Write a note about it that will be shared along with a link to the activity (some platforms, like Facebook, don't use this text). When you're happy with your work, press Continue →
On the next screen, choose who you want to share your activity with:
Friends is a list of your friends on Racefully.
Tribes allows you to choose a Tribe to share with (it will be shared to the Tribe chat), and you can also select individual Tribe members to share with by selecting the down arrow to the right of the Tribe name.
Social allows you to share your activity through the social apps you have on your phone.
Contacts accesses your address book to choose people to email your activity to.
When you've finished choosing, press Continue → again and your activity will be shared.
