Rogelio Chirino (born December 23, 1946) is a Cuban sprint canoer who competed in the early 1970s. He was eliminated in the repechages of the K-2 1000 m event at the 1972 Summer Olympics in Munich. Canoe sprint, which is referred to by the IOC as "canoe/kayak sprint", is one of the two forms of the canoeing disciplines that are featured in the Summer Olympics, the other being canoe slalom. Marathon racing is not an Olympic sport. In non-Olympic years, the main events are the World Championships. Marathons are long distance races on rivers, lakes, estuaria or open sea. The course may include obstacles such as shallows, rocks and portages. Under ICF rules, the minimum distances for international races are 20 km for men, and 15 km for women. The races may be divided in several parts and/or several days. World Cup and World Championship races normally are about 35 to 40 km long.
