The Women's omnium at the UCI Track Cycling World Championships was first contested in 2009 in Poland.
The format of the multi-race endurance event ("Omnium" coming from the Latin Omnia, for all) has evolved rapidly since its introduction in 2009.
Six cyclists have won the title more than once, taking two gold medals each: Laura Trott and Katie Archibald, both of Great Britain, Tara Whitten of Canada, Sarah Hammer and Jennifer Valente of the United States, Kirsten Wild of the Netherlands in 2012 & 2016, 2017 & 2021, 2010 & 2011, 2013 & 2014, 2022 & 2023, and 2018 & 2019 respectively.
Trott's three silver medals to Wild's one silver and two bronze medals makes Laura Trott, now Laura Kenny, marginally the most successful athlete overall in the history of the event.
Along with Katie Archibald's 2017 and 2021 gold medals and Lizzie Armistead's silver, it also makes Great Britain the most successful nation in the event.
