Pedestrianism is a competitive sport that involves walking long distances, often over a set period of time. It gained popularity in the 19th century, particularly in the United States and the United Kingdom, where events could last for days or even weeks. Participants, known as pedestrianists, would race on tracks or in open spaces, and the sport attracted large crowds and significant betting. The rules of pedestrianism typically required competitors to maintain a walking pace, with specific guidelines to ensure they did not run. This sport is considered a precursor to modern race walking, which is now an Olympic event. Over time, pedestrianism declined in popularity, but it laid the groundwork for future walking competitions.
