 Isinbayeva will aim to claim her first World gold in Helsinki |
Russian Olympic champion Yelena Isinbayeva soared to yet another world pole vault record in Lausanne. The 23-year-old added an extra centimetre to her own outdoor mark, clearing 4.93m in Switzerland.
It is the 14th world record of Isinbayeva's career and comes just over three months after she broke her own indoor mark in Lievin.
The Russian, whose indoor mark stands at 4.89m, has yet to clear the milestone 5m-mark in competition.
"It's fantastic for me, I'm so happy," Isinbayeva said. "It's not easy, even if it looks easy.
"I don't know how high I can jump, maybe 5.10 or even 5.15. I just don't know my potential."
Her coach Yevgeny Trofimov claims Isinbayeva has already surpassed 5m in training.
But the Olympic champion receives a $50,000 bonus each time she breaks a world record, so she is likely to take it one step at a time.
She has set herself the target of beating male counterpart Sergei Bubka's haul of 35 world records in the event.
