Problem: Given the question: Information:  - Richard Douglas `` Dick '' Fosbury ( born March 6 , 1947 ) is a retired American athlete who competed in the high jump , and is considered one of the most influential athletes in the history of track and field . Besides winning a gold medal at the 1968 Olympics , he revolutionized the high jump event , inventing a unique `` back - first '' technique , now known as the Fosbury Flop , adopted by almost all high jumpers today . His method was to sprint diagonally towards the bar , then curve and leap backwards over the bar , which gave him a much lower center of mass in flight ( it was actually below his body ) than traditional techniques . He continues to be involved in athletics and serves on the executive board of the World Olympians Association In 2014 Fosbury ran for a seat in the Idaho House of Representatives .  - Cross country running is a sport in which teams and individuals run a race on open-air courses over natural terrain such as dirt or grass. Sometimes the runners are referred to as "harriers" (dogs). The course, typically long, may include surfaces of grass, and earth, pass through woodlands and open country, and include hills, flat ground and sometimes gravel road. It is both an individual and a team sport; runners are judged on individual times and teams by a points-scoring method. Both men and women of all ages compete in cross country, which usually takes place during autumn and winter, and can include weather conditions of rain, sleet, snow or hail, and a wide range of temperatures.  - The 1968 Summer Olympics (Spanish: "Juegos Olímpicos de Verano de 1968"), officially known as the Games of the XIX Olympiad, were an international multi-sport event held in Mexico City, Mexico, in October 1968.  - The World Olympians Association (WOA) is an association of olympic athletes ("Olympians") from all over the world, to promote the dissemination of Olympic ideals and fair play, advance environmental protection, educate against doping and drug use, supply educational resources, work against violence and intolerance, support diversity and equality, contribute to sport-related charities, host special hospitality centres, involve Olympians in social support, display positive role models, advance sport management and promote a culture of which sport is an important part.  - Road running is the sport of running on a measured course over an established road (as opposed to track and field and cross country running).  - Track and field is a sport which includes athletic contests established on the skills of running, jumping, and throwing. The name is derived from the sport's typical venue: a stadium with an oval running track enclosing a grass field where the throwing and jumping events take place. Track and field is categorised under the umbrella sport of athletics, which also includes road running, cross country running, and race walking.   - The Fosbury Flop is a style used in the athletics event of high jump. It was popularized and perfected by American athlete Dick Fosbury, whose gold medal in the 1968 Summer Olympics brought it to the world's attention. Over the next few years the flop became the dominant style of the event and remains so today.  Before Fosbury, most elite jumpers used the straddle technique, Western Roll, Eastern cut-off or even scissors jump to clear the bar. Given that landing surfaces had previously been sandpits or low piles of matting, high jumpers of earlier years had to land on their feet or at least land carefully to prevent injury. With the advent of deep foam matting high jumpers were able to be more adventurous in their landing styles and hence experiment with styles of jumping.    What is the relationship between 'dick fosbury' and '1968 summer olympics'?
