Swimming at the 1964 Summer Olympics – Women's 400 metre freestyle
Introduction The '''women's 400 metre freestyle''' event at the 1964 Olympic Games took place between 17 and 18 October. This swimming event used freestyle swimming, which means that the method of the stroke is not regulated (unlike backstroke, breaststroke, and butterfly events). Nearly all swimmers use the front crawl or a variant of that stroke. Because an Olympic-size swimming pool is 50 metres long, this race consisted of eight lengths of the pool.
