London: Five things to look out for

1. Harrison returns to world record – 100m Hurdles

Two years ago, Keni Harrison shocked the world by running an astonishing, world record breaking 12.20 at the London Diamond League. This weekend, she returns to the scene of her greatest triumph knowing that she needs points to guarantee a place in the IAAF Diamond League Final. While Brianna McNeal and Sharika Nelvis have already qualified, the level of competition is so high in the women’s 100m hurdles this year that the race for the remaining spots has gone down to the wire. London is the last chance to pick up points, and while the likes of Harrison and Christina Manning will be hoping to cling on to a qualifying position, others such as Tobi Amusan and Isabelle Pedersen will be hoping to break into the top eight.

"This meeting is tougher than a world championships," Pedersen told diamondleague.com. "The depth of quality means that the the 100m hurdles is the toughest event in track at the moment. It’s going to be an interesting three or four weeks before the Final."

2. Coleman and Ujah eye Final spot – 100m

In the men’s 100m too there are several big names who are yet to nail down their place in the Final, and a few who might yet miss out. Fresh from victory in Rabat, Christian Coleman will be hoping that he can seure qualification with another win in London on Saturday. Yohan Blake, meanwhile, will be hoping to edge closer to the top eight, as will local heroes Zharnel Hughes and Adam Gemili. 

3. Chelimo and Edris eyeing redemption – 5000m

Paul Chelimo and Muktar Edris were among the handful of athletes who were pipped to the post by Mo Farah in last year’s dramatic 5000m IAAF Diamond League Final. Chelimo and Edris will be looking for redemption this year, and both are well placed to secure qualification as they head to London, the last meet before the Final. 2015 and 2016 Diamond Trophy winners Yomif Kejelcha and Hagos Gebrhiwet are also looking to pick up enough points for passage to the Final, while standings leader Birhanu Balew also lines up in the British capital on Saturday.

4. Rutherford’s return – Long Jump

The Olympic Stadium in London was the scene of Greg Rutherford’s finest hour, as he secured the gold medal at his home Olympics in 2012. A few years later, he finished third here at the Anniversary Games on his way to winning the Diamond Trophy in 2015. It will be an emotional return for the British long jumper, who comes up against some of this year’s top performers on Sunday. Luvo Manyonga and Jeff Henderson have already booked their place in the Final, while Henry Frayne and Ruswahl Samaai will be hoping to do so with a big performance in London. 

5. Lasitskene looks to bounce back – High Jump

Mariya Lasitskene has looked unstoppable in recent years, and her winning streak of 45 was the second longest in women’s high jump history as she plotted a seemingly inevitable course for another Diamond Trophy. All the more surprising, then, that Lasitskene was toppled in Lausanne, finishing third behind Mirela Demireva and Yuliya Levchenko. The Diamond Trophy holder will be out to prove she is still the undisputed number one in London, as she faces Levchenko again. Both women have already qualified for the Final, but London could be a chance for British athlete Morgan Lake to break into the top 12, as she hopes to exploit home advantage and propel herself up the standings.
