There are 10 obstacles in a course and each obstacle has a maximum of 10 points. These points are awarded as maximum 5 points for correct technical completion of the obstacle and maximum 5 points for good horsemanship. Good horsemanship is judged on relationship and communication between horse and handler, which can be evidenced by the handler leading the horse with a "smile" in the line, the horse having a positive expression and whether the handler needs to make corrections to how the horse is completing the obstacle.
These competitions are split into on line competitions (using a lead rein that is at least 10 feet long) and liberty competitions. There are levels within the league, from Starter level through to Advanced 1* level, allowing you and your pony to compete against partnerships of a similar experience to yourself and to progress from relatively simple courses to very challenging ones!
There are also some real time competitions available, depending on how active the Horse Agility community is in your area. These competitions may be organised by a Horse Agility Accredited Trainer (HAAT) or by a local group of Horse Agility members, but for the results to be recognised in the international league the real time competition must be judged by a registered HAAT.
