The team format has varied in some seasons. Four seasons featured 12 teams of two rather than the standard 11, while the "Family Edition" featured ten teams of four players, some of whom were young children. Seasons 26 and 29 included teams made up of people who met for the first time just prior to the start of the race. Some formats featured as few as eight (as seen in the Chinese celebrity series) or as many as 14 (fourth and fifth seasons of the Israeli version) or 16 (fifth Australian season) teams.
