Blimey, we're halfway through already?!

As you can see, the sun has been shining in Tokyo today and it's certainly been the hottest day of the championships - although I am happy to report that the humidity has dropped as a result. Phew.

On their way into the stadium, the fans are guided from the station along a purple track, reminiscent of that used at last summer's Olympics at the Stade de France.

What a spectacular stadium it is and how great it is for Japan that it's getting used as it was intended when it was built for the Tokyo Games four years ago.

Another well attended evening session is under way and, as it did last summer, GB will hope the men's 1500m can produce at least one medal.

And maybe, just maybe, more than that.

India's star athlete Neeraj Chopra begins his world title defence in the men's javelin qualifying on Wednesday, with the final taking place on Thursday.

Chopra made history two years ago in Budapest as he became India's first world champion, with Pakistani rival Arshad Nadeem finishing second.

Nadeem got his revenge at Paris 2024 by claiming gold, with Chopra having to settle for silver after winning gold at the Tokyo Games.

Chopra is one of just three men to break the 90m barrier this season - however, the other two have thrown further.

Germany's Julian Weber and Brazil's Luiz da Silva will be looking to build on their impressive seasons to compete for a medal this time round in Tokyo.

Chopra and Nadeem will face off in Group A, with Weber and Da Silva taking part in Group B.

There is no British representation in the women's pole vault final, after Molly Caudery suffered injury heart-break during the warm-up before the start of the qualifiers on Tuesday.

With Olympic and world champion Nina Kennedy absent through injury, the field is wide open.

Katie Moon of the United States is the favourite - she arrived in Tokyo off the back of back-to-back Diamond League victories, and progressed from the qualifiers in joint-second place.

Brazil's Juliana De Menis Campos and New Zealand's Imogen Ayris unexpectedly topped the rankings in qualifying, and will have to maintain their level if they are to fight off the likes of six-time global medallist Sandi Morris, 2025 world leader Amanda Moll and Angelica Moser, European champions indoors and out.

Qualification for the men's triple jump is underway, with Italy’s Andy Diaz Hernandez the favourite this year.

He currently holds the season best distance with a national record of 17.80 metres, and won the world indoor title in March.

Diaz Hernandez took bronze at the Paris Olympics last year, with Spain's Jordan Diaz Fortun claiming gold - he will also be competing in Tokyo.

Other athletes to watch out for include Jamaica's Jordan Scott, who won four Diamond League meetings this season, and China’s Wu Ruiting, who recorded a personal best 17.68m jump last month.

Great Britain and Northern Ireland equalled their best haul of 10 medals to finish seventh at the 2023 World Championships, bringing home two gold medals, three silvers and five bronze.

They also achieved GB's best return at an Olympics for 40 years with 10 athletics medals at Paris 2024.

And, while 31 other countries have already won a medal, the British team will believe that they can produce a strong finish to these championships.

We are hoping for Team GB medals today.

We would have liked to see more sooner but there have been disappointments and things that have not gone to plan - Molly Caudery for example.

We shouldn't panic too much because there are opportunities today.

There was disappointment yesterday as all three of Great Britain's runners in the men's 400m, including Olympic silver medallist Matthew Hudson-Smith, missed out on the event's final.

Great Britain are yet to get on the medal table, so who else has missed out?

2024 world indoor pole vault champion Molly Caudery suffered an injury while warming up before her qualification event, while Emile Cairess - fourth at last year's Paris Olympics - could not complete the men's marathon.

Elsewhere, 2023 world bronze medallist Zharnel Hughes and world indoor 60m champion Jeremiah Azu were unable to reach the men's 100m final.

Amber Anning, Max Burgin and Ben Pattison were among the athletes to maintain their medal pursuits on Tuesday night.

Meanwhile Keely Hodgkinson and Georgia Hunter-Bell start their women's 800m campaign on Thursday, Katarina Johnson-Thompson gets going in the heptathlon on Friday, while Max Burgin in the men's 800m and the relay teams stand decent chances of picking up medals.

So here's how the medal table looks after day four of the World Athletics Championships.

The United States lead the way with eight medals - including six golds - while Great Britain are yet to get on the board.

Is that going to change today?
