Russian pole vault queen Yelena Isinbayeva hopes to treat athletics to its first individual world record of the year when she competes in this weekend's IAAF indoor championships.
"That is my goal," the 27-time world record holder told a news conference ahead of the three-day meeting.
"I am in Doha for the first time in my life and I would like to make my competition unforgettable," said the Russian, who set the current world indoor record of 5.00 metres in 2009. Her best this season is 4.85 metres.
She and Ethiopian 3,000 metres seasonal leader Meseret Defar are bidding for fourth consecutive global indoor titles.
That would help make up for her failure to win the world outdoor championship last year in Berlin when she no-heighted.
"I still use it like a huge motivation," said the world indoor and outdoor record holder. "I will never forget my defeat in Berlin."
Top flight competition is also expected in the the men's 60 metres hurdles, the men's 3,000 metres as well as the women's high jump, pentathlon and 60 metres.
The hurdles race will bring together Cuban outdoor world record holder Dayron Robles, American two-time former winner Terrence Trammell and recovering Chinese former Olympic champion and record holder Liu Xiang.
"People want to see the three of us compete with no one injured. I don't think we've really had that to actually occur," said Trammell, who has the year's leading time of 7.41 seconds.
Liu, the defending champion, will be making his first global championship appearance since an Achilles injury forced him out of the 2008 Beijing Olympics.
Although the Chinese team's technical leader said it would be almost impossible for Liu to win, Trammell said he expected Liu to be a contender.
The men's 3,000 metres also promises to be intriguing with Kenyan-born American Bernard Lagat matched against Ethiopian defender Tariku Bekele.
Lagat will be chasing his second gold medal in the event six years after winning for Kenya in 2004.
The men's 60 metres lost much of its glitter when American favourite Ivory Williams tested positive for marijuana, making him ineligible for the championships.
British European champion Dwain Chambers is now favourite for the title.
In the women's high jump, Croatian world outdoor champion Blanka Vlasic also has world-record ambitions. Her best this season, 2.06 metres, is only two centimetres short of the world record.
Another Berlin winner, Britain's Jessica Ennis, is the pentathlon favourite despite a foot injury.
"I had to change my preparations, but I feel I am in good shape," Ennis said.
