Dance Marathons (also called Walkathons), an American phenomenon of the 1920s and 1930s, were human endurance contests in which couples danced almost non-stop for hundreds of hours (as long as a month or two), competing for prize money.

Dance marathons originated as part of an early-1920s, giddy, jazz-age fad for human endurance competitions such as flagpole sitting and six-day bicycle races. Dance marathons persisted throughout the 1930s as partially staged performance events, mirroring the marathon of desperation Americans endured during the Great Depression.
In these dance endurance contests, a mix of local hopefuls and seasoned professional marathoners danced, walked, shuffled, sprinted, and sometimes cracked under the pressure and exhaustion of round-the-clock motion. A 25-cent admission price entitled audience members to watch as long as they pleased.

Dance marathons were held in Spokane, Seattle, Yakima, Wenatchee, Bellingham, and elsewhere. They occupied a slightly disrespectable niche in society, and many towns banned them, finding them disruptive, disturbing, and even repugnant.
