Welcome to the World Athletics Watch Party, join the conversation on Twitter with our hashtag #WatchWorldAthletics. Returning to their vintage best, the USA regained the men’s 4x400m world title with the fastest time for 11 years with a typically dominant performance. Having surprisingly forfeited the title to Trinidad & Tobago two years ago in London their team of Fred Kerley, Michael Cherry, Wil London and Rai Benjamin stormed around four laps of the Khalifia International Stadium in a world-leading time of 2:56.69. In the women's race, living to their favourite’s billing, the US squad dominated the women's 4x400m, blitzing the field with a 3:18.92 world-leading performance. Poland, anchored by European champion Justyna Swiety-Ersetic, took silver in 3:21.89, a national record for the quartet.
