Select if you are tracking your own mileage only.
Select if you are part of a group in which all participants are doing the same mileage and a single team leader will manage your Challenge (e.g., family, scout group, teachers).
Select if participants want to do different mileages, but also track their results together. Designate a team leader to signup first and receive a JOIN CODE to share will all participants. Participants use the Join Code to register individually. If you have a join code, go directly to Join a Challenge tab.
Sign up here only if you are joining an organizational challenge. Otherwise, sign up under the CREATE A CHALLENGE tab
