The 2010 World Junior Championships in Athletics was an international athletics competition for athletes under the age of 20 which was held at the Moncton Stadium in Moncton, New Brunswick, Canada from 19 to 25 July 2010.[1] A total of 44 athletics events were contested at the Championships, 22 by male and 22 by female athletes. It was the second time that the event took place in Canada, after the 1988 edition in Sudbury. This became the last event announced by Scott Davis.
Katsiaryna Artsiukh of Belarus, the winner of the women's 400 m hurdles title,[2] had a positive test for Metenolone (a banned steroid) on the day of her victory. She was banned from the sport for two years.[3]
The competition opened the evening of 19 July and, following a ninety-minute light and music presentation, the championships were officially opened by the Prime Minister of Canada Stephen Harper and Gary Lunn, the Minister for Sport. One event was held on the first day, the women's 3000 metres, and the Prime Minister awarded Mercy Cherono with the first gold medal of the competition.[4]
