Young Armand Duplantes is close to the top of the world pole vault, but the European champion says he wouldn't have reached it if it weren't for family.

The 19-year-old Swede has won six meters twice this year and has become a candidate for a medal at the World Athletics Championships, which begins on Friday in Doha.

His father, Greg, a former pole vault competitor, trains him in style while his mother, Helena, a former Swedish seven-seater, is adapting.

"My father may have helped me reach 5.80 meters, but certainly I owe a similar, if not greater, thanks to my mother, who brought me to six meters," he told Reuters.

Over the past four years, he has trained with his mother about five times a week for one day with his father to improve his style.

He explained that they helped him design a training plan that would allow him to reach his peak during the exceptionally late World Championship.

"I didn't take part in many tournaments earlier this year," he said. "It was a plan not to exhaust myself early because I want to reach the top of my level by October, which is a little strange."

He spent the summer in Sweden visiting his mother's family and competing in local tournaments.

In 2015 he decided to represent Sweden instead of the United States at the Under-18 World Championships.

"I was not prominent at the time. I was achieving 5.25 meters or so. I think some did not care, Sweden and athletics in my heart, I never look back, I don't regret this decision," he said.
