Before 1967 and since its inception in 1897 - making it the world's oldest annual marathon - the Boston Marathon was strictly men-only. The only woman to have tried to complete it was Bobbi Gibb who, a year before, dashed out of a bush and over the finish line. In 1967, Switzer registered officially under a gender neutral name - K.V. Switzer - was given a bib with the number 261 on it and wore a baggy grey tracksuit that ensured preoccupied start line officials assumed she was “just one of the guys”.
Physical fitness is a general state of health and well-being and, more specifically, the ability to perform aspects of sports or occupations. Physical fitness is generally achieved through correct nutrition, moderate-vigorous physical activity, exercise and rest. It is a set of attributes or characteristics seen in people and which relate to the ability to perform a given set of physical activities.
