Great Britain holds the London Athletics Meet women’s 4 × 100 m relay record of 41.55 seconds.
The British quartet of Dina Asher-Smith, Imani-Lara Lansiquot, Amy Hunt and Daryll Neita ran 41.55 at the 2024 London Athletics Meet. Their time was a meeting record, a British record-equalling performance and a world lead at the time.
The mark matched Great Britain’s 41.55 from the Tokyo 2020 Olympic Games, held in 2021. Because relay records belong to teams, the canonical quiz answer is the nation rather than any one runner, even though the athletes are often listed alongside the mark.
The United States, Jamaica and the Netherlands are frequent alternatives because all have produced elite women’s sprint relay teams. However, the question asks for the London meeting record, not the global record. The world record remains 40.82, set by the United States at London 2012.
