Caster Semenya produced another dominating performance breaking her South African 1000m record at the ISTAF Berlin meeting.
Lining up at her favourite meeting, Semenya was in a class of her own practically running on her own for the majority of the race to claim victory in a time of 2:30.70.
She shaved 0.31s off the previous time she set at the Rabat Diamond League meeting in July lifting her to fifth place on the world all-time list.
“It was a great race, a little bit tiring, as I was leading the whole field but I am happy about the time,” Semenya said.
“It is not only about running fast, it is about feeling your body and we have done what we could.
“The crowd was fantastic, it was great being invited to the ISTAF, this meeting and the stadium are amazing.”
Producing a peerless run, Semenya set the pace in front to finish first with the rest of the field following way behind.
Uganda’s Halima Nakaayi finished in second place with a time of 2:34.88 with Nelly Jepkosgei of Kenya bagging bronze in 2:35.30 with both posting national records.
Semenya won her third straight Diamond League series victory in the 800m at last week’s Zurich meeting adding to the 2016 and 2017 titles.
She won the two-lap final from gun to tape clocking 1:55.27 with Ajee Wilson of the United States finishing second in 1:57.86.
The two-time Olympic champion will bring her season to an end at the Continental Cup in Ostrava where she is expected to line up in the 400m and the 800m.
