The format is simple: competitors are divided into two categories - ENDURO or SPRINT depending on what type personal watercraft they ride and the style of riding they enjoy. Then, depending on the quality of the field, the category is divided by ability into Pro or Amateur. If the field is not sufficient in size to split the classes then the classes will run under Pro/Am class rules.
The races mainly take place on the coast, but races can be held on lakes or rivers. The tracks are large enough to accommodate the varying levels of ability and each race lasts for 30 minutes + 1 lap in duration.
