4 × 400 m relay (indoor), women

What to remember

The NCAA Division I Indoor Championships were the setting for this relay: in Albuquerque, on March 11, 2023, Amber Anning, Joanne Reid, Rosey Effiong and Britton Wilson ran the indoor 4 × 400 m in 3 min 21.75 s. The team brought together one British, one Jamaican and two American runners, for an average of 28.550 km/h.

The 4 × 400 m, known as the "long relay", has four runners each cover 400 metres before passing the baton, for 1600 m in total. It is traditionally the final event of a track meet.

Amber Anning competed in college for LSU and Arkansas. She went on to win two bronze medals at the 2024 Paris Olympics, in the women's and the mixed 4 × 400 m relays, and set the British 400 m record of 49.29 s when finishing fifth in the Olympic final. In 2025 she became world indoor 400 m champion.
