2017 IAAF World Championships in London

It's been an exhilarating start to the 16th edition of the 2017 IAAF World Championships, as the British capital, half a decade on from the London Olympics, once again becomes a platform for the world's finest athletes to compete fiercely on track and field. Now into the 5th day, this year's World Championships are taking place from 4 to 13 August 2017 at the London Stadium, with coverage provided by the BBC across TV, radio and online.

Presented by former Wales international gymnast  Gabby Logan , also joining the BBC Sport team is Olympic legend  Michael Johnson  to provide his expert opinion and analysis. Further commentary comes from the likes of Steve Cram , who won 1500m gold at the first World Championships in 1983; Andrew Cotter, the Scottish sports broadcaster; Steve Backley, formerly the world record holder for javelin throwing; and Ore Oduba , the One Show presenter and Strictly Come Dancing winner.

Let's take a look at the highs and lows so far:

Day 1 - Friday 4th

- British distance legend Mo Farah, who will switch from global track to road racing next season, stormed through a gripping 10,000m race to win a gold medal. He will compete in the 5000m on the second weekend.

Day 2 - Saturday 5th

- Jamaican sprint superstar and eight-time champion Usain Bolt's race "fell apart" in the 100m final when he was beaten by American competitor Justin Gatlin, who was controversially booed by a surprised crowd.  The 4x100m relay is yet to come.

- Despite being tipped to make the podium, British athlete Katarina Johnson-Thompson missed out on a heptathlon medal,  after failing to recover from a poor high jump, and instead finished fifth.

Day 3 - Sunday 6th

- US athlete Tori Bowie produced an exciting finish to win gold in the women’s 100m final, beating Marie-Josée Ta Lou on the line.

Day 4 - Monday 7th

- Much anticipation has been built for Britain's Laura Muir in the upcoming 5,000m, who was just pipped to a medal when she came fourth in the women's 1500m final.

Day 5 - Tuesday 8th

- South African rising star Wayde van Niekerk won a gold in the 400m. Controversy surrounds his dominant display, since one of his rivals, Botswana's Isaac Macwala, was not allowed to race following a norovirus outbreak, despite asserting that he was fit enough to compete. Nonetheless, a golden 200m-400m double could be on the horizon for Van Niekerk.

Day 6 - Wednesday 9th

- After receiving a written request from the Botswanan federation, Isaac Macwala, now declared fit to compete following a medical examination, was allowed to race solo in the 200m semi-finals. After running a time of 20.20 seconds, he beat the qualification time of 20.53 and advanced to the finals. Controversy remains, however, as the focus of his training was for the 400m.

- Meanwhile, Norway's Karsten Warholm won 400m hurdles gold.

Day 7 - Thursday 10th

- Van Niekerk came second in the 200m, and Macwala sixth, both beaten by Turkey's Ramil Guliyev.

- The US's Kori Carter won the 400m hurdles final with compatriot Dalilah Muhammad in second place.

With more medals to be won by individuals competing at the peak of human performance, there's plenty to still experience over the course of this week through to Sunday. Will the legacy of London 2012 overshadow British success in the athletics despite the home advantage? Is Farah's injury likely to affect his performance in the 5,000m on Saturday? Will Bolt retire from his glittering career with a bang in the 4x100m relay? Sports fan around the globe continue to watch with excitement.
