Betty Heidler was the pre-event favourite: she was undefeated that season, held the four best marks of the year, and had broken the world record with a throw of 79.42 m in May. Tatyana Lysenko, a former record holder, was ranked second prior to the championships. Yipsi Moreno and Zhang Wenxiu (both medalists at the 2008 Olympics) were both in good form that season, as was Kathrin Klaas (fourth in 2009). Zalina Marghieva, Alena Matoshka, Jennifer Dahlgren were other entrants ranked in the top ten. The 2009 world champion Anita Włodarczyk was not expected to compete due to a back injury.
