Ultimate Frisbee is a team sport played with a flying disc, self-refereed. One of the core values of Ultimate is the Spirit of the Game.
The objective of the game is to score points. At each end of the field there are end zones, and the goal is to move the disc into those zones through passes (running with the disc is not allowed) without it touching the ground, avoiding interception by the opposing team. Catching the disc in an end zone scores a point.
There are plenty of tournaments celebrated in Spain yearly, both on grass and on the beach.
One remarkable feature is that the large majority of them are played co-ed, which makes ultimate an ideal and unique sport to share with all your friends.
