Hello @rodjphoto, thanks for joining the Fitbit Community, it's a pleasure for me to welcome you! 
At this moment, Adventure Races are only available for users in Canada and Australia, but will be coming soon to other racers around the world.
I hope this resolves your inquiry, if there's anything else I can do for you, please keep me posted!

Hello @rodjphoto, I hope you're having a great day, thanks for taking the time to reply!
If your friends are now able to see the Adventure Races feature in their apps is possible that someone in Canada or Australia has invited them to join one race.
If a user in Canada or Australia invites a user in a different location (not Australia or Canada) to the challenge, that user will be granted access to the adventure race feature and be able to participate in adventure race challenges.
I hope this can be helpful, please feel free to reply in case you need anything else.
