United States set new world record in mixed 4x400M relay final.

The USA win the first mixed 4x400M relay, as they take home gold at Doha in the World Athletic Championships.

The United States broke the world record by three seconds with a time of 3:09.34, beating their own previous world record set earlier on in the championships qualifying heats.

The US opted to change their entire starting quartet for the final, as Michael Cherry ran the anchoring leg to secure gold for the Americans.

America’s Allyson Felix added another gold to her collection as she collected her 12th gold of her career, as she returned to action after giving birth only a mere 10 months ago.

The victory for Felix and America sees her become the all-time gold medal winner suppressing the previous record held by Usain Bolt.

Felix, added an additional 13th gold medal later on in the championships running in the preliminary round of the women’s 4x400M relay.

Jamaica took home silver in second place setting a national record of 3:11.78, with Bahrain rounding out the medals with Bronze and setting an Asian record time of 3:11.82.


The Polish team took a different tactical approach to the other runners, which saw their two male athletes Wiktor Suwara and Rafał Omelko run first and build a lead over the field in the hope of Iga Baumgart-Witan and Justyna Święty-Ersetic could see them home to gold.

However, the gamble was unsuccessful as Święty-Ersetic was closed down by Michael Cherry and Jamaica’s Javon Francis on the final lap, as athletes from Bahrain and Great Britain & Northern Ireland also overtook her as Poland crossed the line in 5th place.
