Hallberg Hossain was one of the favorites before the competition, despite the fact that she was born as late as 23 December 2006 and you can compete in U18 if you were born on 1 January 2005 and later.
In the fourth jumping round she stood for the giant jump 6.39 and thus won by 9 centimeters over the second Likar from Slovenia, who has the world year best in the class.
She thus took Sweden's third medal in the championship.
The 15-year-old is one of Swedish athletics' greatest talents.
She took bronze in the senior-SM as late as last winter and at the same age, only Erica Johansson and Tilde Johansson have jumped further.
As a 12-year-old, she also broke the world record in the high jump with 1.77.
