United States break new world record in mixed 4×400 metres relay final
The United States win the first ever mixed 4×400 metres relay gold medal in Doha at the World Athletics Championships.
Michael Cherry crossed the line for the USA setting the record time of 3:09.34 after team-mates Wil London, Allyson Felix and Courtney Okolo had run the first three quarters of the race at the Khalifa International Stadium.
Unbelievably five different teams ran under the previous world record set the night before in the heats by the USA at 3:12.42 .
Poland and Great Britain both ran under the previous world record finishing fifth and fourth respectively, Bahrain finished third picking up bronze medals, Jamaica finished second, whilst the USA swept up the gold medals.
United States team member Allyson Felix earned her 12th gold medal at a world championship that saw her surpass Usain Bolt as the most decorated athlete on the world championship stage.
All eight teams competing in the final adopted the same strategy of having the two male competitors starting and finishing the race with their two female team-mates running in second and third position apart from Poland.
Poland elected to have their two male runners start the race, with their two female athletes running in third and fourth position on the track in order to try and gain an advantage over their opponents.
Although they got off to a good start and led for much of the race, they ultimately came undone in the closing stages, dropping outside of the medal places.
Team GB may also feel disappointed to miss out on a medal even though they only just qualified for the final after finishing as fastest loser after the heats.
A poor change over between Emily Diamond and Martyn Rooney saw Rooney hesitate before losing ground on Bahrain’s Abbas Abubakar Abbas in the final charge towards the finishing line.
The mixed 4×400 metres relay will be at the Tokyo 2020 Olympic Games for the first-time next year.
