The International Canoe Federation states standard distance races are at least 10 kilometres (6.2 mi) without an upper limit, while short distance races are between 3.4 kilometres (2.1 mi), and 10 kilometres (6.2 mi).

Some events attract thousands of competitors and are staged over several days.

Example classes are: K refers to a kayak, C a canoe and OC to an outrigger.

K1, K2, K4, C1, and C2 classes are permitted in International Canoe Federation events.
