Co-ed Summer League follows UPA 11th Edition Rules with the additions noted below:
Like many sports played at a competitive level for many years, Ultimate has many rules in its 11th edition rule book. For those new to the sport there are 10 simple rules to get you started. One of the most fundamental of these rules, and part of what makes it stand out among other competitive sports, is the rule of Spirit of the Game. All players participating in Co-ed Summer League are required to play within the Spirit of the Game.
One of the primary goals of Gorge Ultimate Co-ed Summer League is to provide a fun, Ultimate playing experience for the greatest number of people. As well, it is to grow the Ultimate playing community in the Gorge, increasing the number of men and women participating to a level that reflects the athleticism of the region. To that end, Co-ed Summer League teams are required to ensure that all members of the team are getting equitable playing time and that all members of the team are involved in plays and drives towards the end zones.
