## Career
### Junior career

Erriyon Knighton started participating in track and field in 2019 as a freshman at Hillsborough High School in Tampa, Florida. During his time there, he ran the second fastest time over 200 meters for an under-18 athlete in world history, clocking 20.33 seconds in the final at the 2020 USA Track & Field Junior Olympics in Satellite Beach, Florida. He also played for Hillsborough's football team as a wide receiver; rated a four-star recruit by 247Sports.com, he received scholarship offers from schools including Alabama, Auburn, Florida State, and Florida.

#### 2021

At age 16 in January, Knighton signed a sponsorship deal with Adidas in his junior year of high school, forgoing his remaining two years of amateur competition at Hillsborough High. On May 2, he broke the 10-second barrier over 100 meters at the PURE Athletics Sprint Elite Meet in Clermont, Florida, with a time of 9.99 seconds, but the wind was over the +2.0 meters per second velocity limit (+2.7) for record consideration.
On May 31, the 17-year-old set the world under-18 best in the boys' 200 meters in a time of 20.11 seconds, breaking Usain Bolt's best by two hundredths of a second. At the US Olympic Trials he would improve that time to 20.04 s in the first round on June 25, and then again to 19.88 s in the semi-finals the following day, breaking Bolt's world U20 record by five hundredths of a second. He then improved his own record to 19.84 seconds in the final on June 27, qualifying for the postponed 2020 Tokyo Summer Olympics.
At the Tokyo Games, Knighton became the youngest male to represent the United States in track and field since Jim Ryun in 1964. On August 3, he finished first in his 200-meter Olympic semi-final heat and qualified for an automatic spot in the final to be run the next day. In the final he finished in fourth with a time of 19.93 seconds.

#### 2022

On April 30, Knighton set an unratified world junior record in the 200 m at the LSU Invitational in Baton Rouge running a time of 19.49 seconds. He achieved 19.69 s at the USA Outdoor T&F Championships in June. Knighton later on went on to place third in the event at the 2022 World Athletics Championships, in Eugene, USA, becoming the youngest ever individual sprint medalist in Championship history. He also became the youngest winner of a Diamond League race with his 200 m victory on September 2 in Brussels.

#### 2023

On July 9, 2023, in Eugene during the USA Outdoor T&F Championships, he won his first senior national title by triumphing in the 200 meters with a time of 19.72 seconds.
At the 2023 World Athletics Championships in Budapest in August, Erriyon Knighton once again stood on a world podium by finishing second in the 200 m final with a time of 19.75 seconds. He was once again beaten by Noah Lyles, who won comfortably with a time of 19.52 seconds.
At the end of the season in September, he finished third in the 200 m final of the Diamond League in Eugene with a time of 19.97 seconds.
Erriyon closed his last season as a junior with 18 times under 20 seconds in the 200 meters, with his top 10 times occupying the 10 best U20 performances of all time in the 200 meters.

#### 2024

He started his season with a 200m indoor race in Liévin, France, where he won in a time of 20.21 seconds.
On March 26, Knighton was provisionally suspended by the US Anti-Doping Agency (USADA) after testing positive for a metabolite of the anabolic steroid trenbolone. In June the USADA accepted Knighton's explanation that the source of the trenbolone was contaminated meat and ruled that he bore "no fault or negligence" for the positive test. He therefore received no sanction.
At the US Olympic trials, he placed third in the 200 m with a time of 19.77 seconds, qualifying for the 2024 Summer Olympics in Paris. During the Olympic Games, Knighton recorded times in the 200m of 19.99 in the heats and 20.09 in the semi-final. In the final, the Knighton finished in fourth place with a time of 19.99 seconds.
In early August, after the Olympics ended, the Athletics Integrity Unit launched an appeal with the Court of Arbitration for Sport (CAS) against United States Anti-Doping Agency's decision regarding Knighton's positive drugs test.
