The London Diamond League returns to the London Stadium, with over 60,000 fans set to attend a festival of athletics.
It will be the largest one-day athletics event this year, and the world’s biggest stars will be turning up to fit such a billing.
Almost one year on from Paris 2024, here are five British Olympians to watch on Saturday.
George Mills – 1500m
The men’s 1500m is one of the most exciting events around at the moment, and George Mills is yet another British talent looking to make his mark on the metric mile.
Jake Wightman and Olympic silver medallist Josh Kerr claimed back-to-back world titles in 2022 and 2023 and Mills has now joined the party after clocking 3:28.36 at the Paris Diamond League last month.
NEW BRITISH RECORD 🔥

George Mills breaks Sir Mo Farah's 5000m record by more than six seconds with a stunning run at the Oslo Diamond League 👏

That put him second on the British all-time list, just behind Kerr and ahead of legends such as Steve Cram, Seb Coe, and Steve Ovett.
Mills also set a new British record in the 5000m of 12:46.59 at the Oslo Diamond League, meaning he arrives in London in red-hot form.
Georgia Hunter Bell – 800m
Georgia Hunter Bell earned a thrilling bronze medal over 1500m at Paris 2024, but she has also proved she is a world-class threat over 800m.
She was part of the iconic trio of Brits that stormed the event last year in London, when Keely Hodgkinson set a new British record and Jemma Reekie also set a new personal best alongside Hunter Bell.
A year on and Hunter Bell is targeting the shorter event once again and hinted earlier this year that her focus may switch fully to two laps of the track.
A strong performance in London amongst a field that includes Reekie and Tokyo Olympic silver medallist Laura Muir would certainly be food for thought ahead of the World Championships in September.
Matt Hudson-Smith – 400m
Matt Hudson-Smith narrowly missed out on Olympic gold in Paris last summer, but that seems only to have fuelled the fire to burn even brighter this year.
Hudson-Smith earned 400m silver in Paris but has eyes on world gold in Tokyo later this year and looks to be shaping up nicely in his preparations.
The Wolverhampton-born star is ranked No.1 in the world in the men’s 400m and clocked 44.10 strolling over the line at the Eugene Diamond League earlier this month.
He lines up amongst an exciting field in London, with extra British interest in Charlie Dobson and the much-improved Toby Harries – both part of the 4x400m relay team that won bronze in Paris.
Add in Botswanan Olympic silver medallists Bayapo Ndori and Busang Kebinatshipi, plus the experienced Vernon Norwood and world leader Zakithi Nene and it is set to be a mouth-watering single lap of the track.
Molly Caudery – Pole Vault
Molly Caudery did not have the Olympics she would have wanted last summer, but the pole vaulter has already shown why she is one of the best in the world this season.
Caudery won the Doha Diamond League in May and jumped 4.80m outdoors in Athens earlier this month.
It has been the perfect way to respond to the disappointment of missing out on the Olympic final, having arrived in Paris with huge momentum following world indoor victory in Glasgow earlier that year.
Caudery is one of just two athletes in the field to have jumped over 4.90m, alongside Tokyo gold medallist Katie Moon, and will hope to put on a show for the home crowd amidst strong competition.
Jazmin Sawyers – Long Jump
It has been a long time coming, but Jazmin Sawyers is back competing and will return to the Diamond League on Saturday.
It will be Sawyers’ first Diamond League competition since September 2023, after the long jumper missed the entirety of 2024 with an Achilles injury.
It also ruled her out of the 2024 Paris Olympics but the Stoke star has fought her way back and has already jumped 6.89m this season, above the standard required for the World Championships in Tokyo and just a centimetre off of her outdoor personal best.
Sawyers has documented her rehab journey on social media, giving fans an incredible insight into what it takes to get back competing.
A home crowd is the perfect way to Sawyers to continue her return, with Olympic heptathlon silver medallist Katarina Johnson-Thompson also in the line-up.
