The entire American line-up was changed between the heat and the final as they stormed to a ninth gold in this event.
In came 400m hurdles gold and silver medallists Dalilah Muhammad and Sydney McLaughlin to join Phyllis Francis and Wadeline Jonathas to clock a world-leading 3:18,92 and comfortably beat Poland’s national record of 3:21.89.
Jamaica took bronze in a season’s best time of 3:22.37 – though not until after they had been disqualified and then reinstated on an eventful evening.
The Great Britain quartet of Zoey Clark, Jodie Williams, Emily Diamond and Laviai Nielsen initially thought they had finished outside the medals as they ran a season’s best of 3:23.02 for fourth place but they found themselves moved up a place on to the podium after Jamaica were disqualified for lining up incorrectly at the second handover.

Carbon Footprint
You'd have had to have been running on a different planet to miss all the recent debate about carbon-plated shoes. The talk of bans and performance enhancement has been so widespread that even non-runners are asking their running friends about the potentially magical footwear.
Trail time
WHEN looking for a trail or off-road running shoe, it’s often all about the grip. However, given that no two paths are the same, careful consideration is required. What’s the terrain like where you’ll wear the shoes the most? If you’ll be negotiating soft, wet and muddy conditions then look for deeper lugs. For tackling gravel tracks and forest trails then more evenly spaced lugs will work better. When it comes to cushioning, consider how hard the ground will be; if it’s soft then you’ll be fine in low-profile shoes, but on those firmer tracks reasonable cushioning will be called for.
Stay neutral
EVOLVING every year, if not month, neutral cushioned shoes are seeing developments in cushioning materials and dynamics at a pace which is nothing short of astonishing. The latest models feature new polymers in the midsoles to give them a cushioned feel while at the same time keeping their weight to a minimum. Give them a spin and choose the most comfortable for mile after mile of shock absorbing running.
Support network
WHEN it comes to ‘over-pronation’, a common question is ‘how much is over?’. With no hard and fast rules, it’s best to choose a shoe that instinctively feels right. Gait analysis can often assist in helping you make this choice and your specialist running store is always a good place to start if in doubt. To help you make that choice, here’s a selection of some of the best ‘support’ shoes around.
Need for speed
THE racing shoe segment of the market is becoming somewhat split. This is partially due to the rise of carbon-plated footwear but also the fact that many shoes are becoming much lighter. Here we take a look at some of the leading contenders to toe the line in.
Gadget show
WITH technological products to enhance every area of life, running is now no different. From headphones to treadmills, the devices to aid performance and recovery are endless. Here we take a look at some of the latest gadgets and gizmos to enhance your training.
