BUENOS AIRES, Oct. 15 (Xinhua) -- Nigeria's Rosemary Chukuma won the high-profile women's 100m race at the Buenos Aires Youth Olympics on Monday.

Chukuma finished third in the first heat with a time of 12.03 seconds, but cut almost a second off her second attempt, crossing the finish line at 11.17 seconds before claiming the gold on Monday.

"I am happy and satisfied because before coming to Argentina I did not have good results," Chukuma said. "I was scared that I would not get what I hoped for at these Games. I started to train in 2016 and I traveled to Australia last year to prepare in this discipline, then continued training in Nigeria."

The Youth Games are set to close on Thursday.
