High Quality Content by WIKIPEDIA articles! The women`s 200 metre freestyle event at the 2008 Olympic Games took place on 11–13 August at the Beijing National Aquatics Center. 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 four lengths of the pool.
