The league is a team based one operating in a ladder tournament format, each team can challenge others above them in the league to a race, which is then run in a 5 v 5 rider format with race points allocated based on finishing position, the team with the highest number of race points is the winner.
The result is then recorded in the league. The league is run in a leapfrog format, this format is commonly used in racquet sports. Teams are free to choose who to play by challenging teams up to 7 above them in the table. If they win they take the loser's position and everyone below moves down a position, hence they leapfrog up the table.
Rather than relying on legacy Zwiftpower categories, teams are bound by ZwiftRacing App rankings, the league mixes all teams, all rankings, together in one league, allowing for a strong team at the upper end of one ranking level to challenge themselves against lower ranked teams of the ranking level above.
