Canoe sprint takes place on a flatwater course and races are contested by two types of boat, canoe (C) and kayak (K). In a canoe, the paddler competes in a striding position using a single-blade paddle, in contrast to the double-bladed paddle used in a sitting position in a kayak. At international level the discipline is competed at four distances from 200m to 5000m, both individually and in teams of up to four. Each discipline is categorised by boat type, number of competitors per boat, gender, and race distance, meaning the example of C2M 500m is the canoe male doubles 500m..
