UCI Track Cycling World Championships – Women's omnium
The Women's omnium at the UCI Track Cycling World Championships was first contested in 2009 in Poland.
The Omnium now consists of six events: a 250m flying start time trial; a 5 km scratch race; an elimination race; an individual pursuit; a 10 km points race; and a 500m time trial. The placing a rider achieves in each event is converted to points, and the rider with the fewest points at the end of the competition wins.. Laura Trott of Great Britain, Tara Whitten of Canada and Sarah Hammer of the United States are the only cyclists to have won the title more than once, taking two gold medals each in 2012 & 2016, 2010 & 2011 and 2013 & 2014 respectively. Trott's three silver medals to Hammer's and Whitten's one makes her marginally the most successful athlete overall in the history of the event. Along with Lizzie Armistead's silver, it also makes Great Britain the most successful nation in the event.
