Sifan Hassan hits the front with three and a half laps to go. Is that going to turn up the burners underneath this race?

Sifan Hassan is in the middle of a leading mob of runners though 3000m in 8:50 odd. There's not going to be a record today.

Sifan Hassan likes to let everyone settle into races and then work into it.

If she's going to go after the record the crunch time will come after 3,000m.

But at the moment it looks like the field are waiting for Hassan to make her way to the front.

Sifan Hassan is the top trend in athletics.

Nine days ago the 26-year-old Dutchwoman sensationally broke the 23-year-old mile record with a 4:12.33 run in Monaco.

Also in the field are kenyan world champion Hellen Obiri and Britain's Laura Weightman who scored a new mile personal best of 4:17:60 behind Hassan in the south of France.

Weightman was just three hundredths outside of Zola Budd’s British mile record, a mark Laura Muir tried – and failed – to break at the last two editions of the Anniversary Games.

She is in for an interesting clash with Eilish McColgan who is focusing on this distance in an impressive season.

The comeback kid is Mutaz Barshim. The Qatari tore ligaments in his left ankle as he took on a world-be world record of 2.46m 12 months ago. He returned to training in April.

Will he be ready to spearhead the host nation's challenge at September's world championships?

This will be a good test of where he is at. World leader Ilya Ivanyuk, an authorised Russian athlete, is in the field. Tom Gale and Chris Baker are in British colours.

Barshim is over 2.24 at the second attempt.

Samuel Tefera showed all his street smarts there. He allowed Filip Ingebrigtsen to lead into the final 150m and then poured on the pace to win in 3:49.45. The Norwegian was 0.15 seconds back.

Jake Wightman was third in a personal best of 3:52.02. Chris O'Hare was seventh with Josh Kerr eighth.

Josh Kerr and Filip Ingebrigtsen are in charge of bringing the pack back...

There is a women's long jump competition with more intrigue than an Agatha Christie novel.

German world leader Malaika Mihambo is joined by American Brittney Reese, who won Olympic and world gold in this stadium in 2012 and 2017 respectively.

Also in the mix is hepathlete Katarina Johnson-Thompson, whose season's best matches that of fellow Briton Shara Proctor and is six centimetres better than Lorraine Ugen.

Lynsey Sharp on BBC One: "It's nice to get a win because I've had a lot of losses over the last couple of years.

"I ran fast in Monaco so it's nice to back that up.

"I had to listen to my head not my heart and make some changes and I did that and am seeing the benefit now."

There were a clutch of solid British performances behind Lynsey Sharp with Alexandra Bell claiming a personal best of 1:59.82 and Shelayna Oskan-Clarke fourth with a season's best in 1:59.83. Adelle Tracey in ninth tripped in the final 10m. She would have had a better time and finish otherwise.
