Allyson Felix becomes USA's most decorated athlete with 4x400m gold

Allyson Felix has become the United States' most decorated track and field athlete in Olympics history after winning gold with her American team-mates in the 4x400m relay – her 11th medal in total.

The gold medal means Felix passes Carl Lewis as the USA's most decorated athlete after a dominant race inside the Olympic Stadium.

Poland continued their impressive relay run in Tokyo, having won the inaugural 4x400 mixed race, with an excellent silver while Jamaica, who had won silver three times in a row, had to settle for bronze. 

The USA could probably have fielded three teams and swept the podium such is their strength over the distance but their 'first team' was dripping with quality. 

Alongside Felix they went for Sydney McLaughlin and Dalilah Muhammad, first and second in the 400m hurdles and both inside the old world record, and Mu Athing, winner of the 800 metres. 

As expected, it was an unstoppable combination as their time of 3:16.85 brought them home almost four seconds ahead of the Poles, whose 3:20.53 was a national record.

Felix's bronze in the 400m on Friday made her the most decorated woman in track and field history and this gold in her fifth Olympics took her tally to 11.

Paavo Nurmi of Finland holds the all-time mark in track with 12 medals from 1920-28. 

That moved her one ahead of Carl Lewis as the top American in total medals and one behind Finnish distance runner Paavo Nurmi from the 1920s as the all-time track and field leader.

However, while history was made for the US, Great Britain missed out on a medal and finished in fifth despite putting in a seasonal best of three minutes and 22.59 seconds.

Ama Pipi made a strong start for Team GB, finishing the first leg in second but the a drop off saw Jodie Williams, Emily Diamond drop down to fifth but Nicole Yeargin couldn't close the gap to the Jamaicans in bronze position.
