At international regattas in canoeing there is three distances on the program. 200m, 500m and 1000m. Men and Women can all participate in these disciplines in both K1, C1, K2, C2, K4, C4 but with that exception that women can only participate in the kayak events.
The same disciplines appears at the European Championships and World Championship, which each is divided in two separate regattas, the Junior/U18 and the Senior/18+. Juniors/U18 does not have 200m in any boat type.
In each event there are 9 lanes and competitors. There are determined special rules about the wide of the lanes. Each lane should be 9 meters wide and a competitor can be disqualified if he is within 5 meters to another competitor because he or she then can get some benefit of "surfing" the others wash.
The 500m event is a kind of mixture of the 200m and the 1000m because it requires both exploitive and endurance. It also became an event on the Olympic schedule in 1976. It is the only event for Women.
