The marathon is a canoe-kayak discipline cousin of the online race. As its name suggests, the event takes place over a long distance, on the river or lake.
The boats respect the rules of the race online with the exception of the weight of the boats. For example, single-seater canoes weigh at least 10 kg and single-seater kayaks 8 kg. The marathon takes place on courses of 20 to 50 km with portages (that is to say a water exit with the canoe, a possible refueling and return on the water).
