Armand Duplantis

Duplantis placed 2nd at the 2019 IAAF World Championships in Doha, Qatar, clearing 5.97 m on his 3rd attempt.

Duplantis began his 2018 season by improving upon the World Indoor Junior Record by jumping 5.83 at the Pole Vault Summit in Reno, Nevada. He later improved his indoor record to 5.88 metres (19 ft 3 in) and reached 6.05 metres (19 ft 10 in) at the 2018 European Athletics Championships. The 6.05 ranked him tied as the No. 5 pole vaulter in history and tied for No. 2 outdoors.

On 11 February 2017, at the Millrose Games, Duplantis jumped 5.75 m (18 ft 10  ⁄4  in) to set the World Indoor Junior Record. That mark was ratified by IAAF. A month later he improved to 5.82 m in the same facility at the New Balance National Scholastic Championships. That mark was not ratified due to incorrect peg lengths being used. On 1 April 2017, Duplantis jumped 5.90 m at the Nike Clyde Littlefield Texas Relays, improving his personal record and setting a new World Junior Record. The jump also became a Swedish senior record by 3 cm. While the IAAF recognized the record with Duplantis representing Sweden, on 2 December 2017, USATF also ratified Duplantis' mark as the American Junior record.

Duplantis cleared 5.49 m (18 ft ​⁄2  in) at a high school meet in Baton Rouge on 6 February 2016, setting a new age 16 world best, world indoor youth best and national high school indoor record; he was the first high school athlete to vault 18 feet indoors. Emmanouil Karalis of Greece, the same age as Duplantis, broke his world marks with a 5.53 m jump only one week later.

Armand Duplantis first tried pole vaulting as a three-year-old at the family's home in Lafayette, Louisiana, and took to the event rapidly; he set his first age group world best at age 7, and his jump of 3.86 m (12 ft 8 in) as a ten-year-old surpassed the previous world bests for ages 11 and 12 as well. As of July 2015, he holds the world best in all age groups from age 7 to age 12; he held the age 13 record until it was broken in May 2015.

In 2015, his freshman year at Lafayette High School, Duplantis set national freshman records both indoors and outdoors and was named Gatorade Louisiana Boys Track & Field Athlete of the Year. As a citizen of both the United States and Sweden, Duplantis could have chosen to vault for either country internationally; in June 2015 it was announced that he had selected Sweden. Duplantis represented Sweden for the first time at the 2015 World Youth Championships in Cali, Colombia; he won gold on countback with a first-attempt clearance of 5.30 m (17 ft ​4  ⁄2  in), improving his personal best by two centimeters and setting a new championship record.

Armand "Mondo" Duplantis (born 10 November 1999) is an American-born Swedish pole vaulter and the current world record holder, pending ratification, with a height of 6.18 metres. Duplantis won gold as a 15-year-old in the boys' pole vault at the 2015 World Youth Championships and holds a number of age group world bests. He won the gold medal at the 2018 European Championships with a height of 6.05 metres (a new under-20s world record), and the silver medal at the 2019 World Championships.
