In Canoe Sprint events, athletes race on a straight course, each boat in a separate lane, over three different distances: 200m, 500m, 1000m and 5000m as well as the 200m x 4 relay. There are kayak events in single (K1), double (K2) and four (K4) boats, and canoe events in single (C1), double (C2) and four (C4) boats. Traditionally, the canoe events have been exclusively for men but there now is a growing women’s contingent since C1W and C2W were added to the 2010 World Championship program. The International Canoe Federation has shown its commitment to gender equity in the Olympic program by adding woman's canoe to the 2020 Olympic program. In a Kayak, the paddler is seated and uses a two-blade paddle, while in a canoe, the paddler is kneeling on one knee, and uses a single-blade paddle. Canoe Sprint became an Olympic discipline in 1936 and its program includes events over the distances of 200m, 500m and 1000m.
