# Salwa Eid Naser

Salwa Eid Naser (née Ebelechukwu Agbapuonwu, born 23 May 1998) is a Nigerian-born Bahraini sprinter who specialises in the 400 metres. She was the 2019 World champion with the third fastest time in history of 48.14 seconds, becoming the youngest-ever champion in the event and also the first woman representing an Asian nation to win that event at a World Championships. The mark places her only behind contested results of Marita Koch (47.60; 1985) and Jarmila Kratochvílová (47.99; 1983). Over the distance, at only 19, Naser was the 2017 World silver medallist. She has also won, as a member of the Bahraini mixed-gender 4x400 m relay team, the 2019 World Championships bronze medal.
Eid Naser was in her signature event, the 2014 Youth Olympic silver medallist and 2015 World Youth champion, before taking her first senior medal which was gold at the 2015 Military World Games. The then 18-year-old skipped the 2016 World U20 Championships, in which a winning time was 51.32 s, to compete directly with the world's best 400 m sprinters at the 2016 Rio Olympics, where she placed injured equal ninth in the semi-finals in 50.88 s. She is a multiple medallist of Asian Games, Asian Championships, as well as other top-level military and pan-regional competitions, both individually and on relays. A two-time 400 m Diamond League champion, as of December 2022, she held the eight fastest Asian results of all time, nine marks in the top 10, and 18 in the top 20.
Naser served a competition ban from 30 June 2021 to February 2023 due to an anti-doping rule violation relating to whereabouts failures.

## Early life

Salwa Eid Naser was born Ebelechukwu Antoinette Agbapuonwu on 23 May 1998 in Onitsha, Anambra, to a Nigerian mother and Bahrain-born father. Her mother had competed as a 100 m and 200 metres sprinter at school and she quickly discovered an ability to sprint. At age 11, in her first competitive race in school, she won the 100 m, and then later the 400 m. Her teacher insisted that she would make a good 400 m runner, so she started to focus on the distance. Before Naser was 14, the family moved to Bahrain. In 2014, she switched allegiance to Bahrain, converted to Islam, and changed her name. When asked in 2017 about her move, she said, "past three years have been a great transition for me" and did not wish to comment on her relationship with the Athletics Federation of Nigeria. In 2019, she said she was happy that people in Nigeria were celebrating her win.

## Career
### 2014–2016: World youth champion

Based in Riffa in Bahrain's Southern Governorate, Naser had her first success at the 2014 Arab Junior Championships, where she was a gold medallist in both the 200 m and 400 m. Following this achievement, she began to take the sport more seriously and set a new personal best of 54.50 seconds at the Asian Trials for the 2014 Youth Olympics. Naser steadily improved her best further at the Olympics, recording 53.95 s in the first round before taking a silver medal behind Australia's Jessica Thornton with a much improved time of 52.74 s. The sprinter then began working with former Bulgarian athlete Yanko Bratanov, who also coached fellow Nigerian-Bahraini athletes Kemi Adekoya and Samuel Francis (banned / disqualified for doping) among others.
In May 2015, she confirmed herself as the continent's best 400 m runner in her age group with a gold medal at the Asian Youth Championships. In June, while in Bulgaria, she set national junior records in the 100 m and 200 m, clocking 11.70 s and 23.03 s respectively. Eid Naser then proved herself among the best globally in the 400 m at the World Youth Championships. A patient run in a tight hijab, what was her own decision, saw her overhaul the more favoured American Lynna Irby in the final stages of the race, and she achieved a lifetime best of 51.50 s to take the gold medal. The final came on the day after Ramadan which allowed her to eat normally before the race, after having fasted during the qualifying rounds. The gold medal made her the second-ever Bahraini woman to win a global-level title, after senior world champion Maryam Yusuf Jamal. Her tactical running was praised by USA's decathlon world record holder Ashton Eaton, who invited her on an all-expenses paid trip to train with him for three days.
Barely 17 years old, in October 2015, she took her first senior title at the Military World Games. Competing in the 400 m against 2012 Olympians Bianca Răzor and Nataliya Pyhyda, she improved to win a gold medal with a world youth-leading and national under-20 record time of 51.39 s, becoming the youngest ever winner of that title. This result was the second-fastest Asian under-18—and 10th fastest world U18—time in history.
Naser had since been coached by Nigerian ex-pat John George Obeya, who had been based in Bahrain for several years.
At the 2016 Summer Olympics in Rio de Janeiro, the 18-year-old made her next progress and won her heat with a personal best of 51.06 s. In the semi-final, she improved even further running 50.88 s, but placed equal ninth overall and did not advance by one place and 0.13 s; her time ranks her however sixth in the final results. Just a week earlier, Naser twisted her ankle, which was first weakened when she was struck by a car aged six. It opened up a fracture, and she was advised not to compete, but she wanted to in her first Olympics. After the Games, she had to take three months rest to treat her leg.

### 2017–2019: World silver medallist and champion

While still a junior, Salwa Eid Naser claimed the silver medal in the 400 m event at the 2017 London World Championships with a new personal best of 50.06 seconds, after winning and each time improving in her heat and semi-final, finally lowering her personal best by a massive 0.82 s. The final took place on a wet surface during light rain. She was last midway through the race, and when she turned for home, she was still only fourth, eventually beating Allyson Felix by 0.02 and being beaten only by Phyllis Francis (photo finish). Shaunae Miller-Uibo had been leading until the last 30 metres when she got the staggers and dropped from first to fourth. At age 19, it made Naser the youngest woman ever to reach the podium over 400 m at a World Championships; she also thrice broke the Bahraini national record. Less than two weeks later, she won in the distance at the Diamond League meeting in Birmingham, and then set even better personal best of 49.88 s in Brussels a week later, securing second place overall in the Diamond Race. This result, the third-fastest world under-20 time in history and an Asian U20 record, would have given her first place in London.
Since November 2017, she has been coached by Dominican Jose Ludwig Rubio.
In 2018, Naser competed at seven 400 m Diamond League events, winning six of them and achieving six marks below 50 seconds. On 30 June, at the Paris Meeting, she won with a new lifetime best of 49.55 s, breaking an Asian record set in 1993 by Ma Yuqin with 49.81 s. On 20 July, at the Herculis meet in Monaco, she greatly improved her PB in a time of 49.08 s to finish second just behind Shaunae Miller-Uibo, who set the circuit record with her result 48.97. It was the fastest women's 400 m race run since 2009, and also the first since 1996 in which two women went below 49.10 s. In August, Naser won the race at the Asian Games in Jakarta. On 30 August, she also won the 4 x 100 m relay final and went on to take silver in the 4 x 400 m relay. She flew to Brussels later that night and won the Diamond League 400 m title just hours later in 49.33 s. A few days later, the sprinter won also Continental Cup held in Ostrava running 49.32 s. In 2018 in total, she won 10 out of her 11 400 m races and recorded seven sub-50-second clockings.
During the 2019 Asian Championships in Doha, Qatar, she claimed gold medals for both the 200 m and 400 m, and also for the 4 × 400 m relay, 4 × 400 m mixed relay and a bronze for the 4 × 100 m relay. In the 2019 Diamond League events, she competed in and won five 400 m races taking her second circuit championship. The sprinter clocked her best time of 49.17 s setting a meet record, on 5 July at the Athletissima in Lausanne, Switzerland.
On 3 October 2019, Naser became the 400 metres world champion at the Doha World Championships in Qatar, the youngest ever and also the first Asian female winner of that title. She improved her personal best, set one year earlier, by a massive 0.94 s, and her result of 48.14 seconds had been the fastest since 1985 – that is for 34 years (when Marita Koch set a world record of 47.60), the second-fastest at a World Championships (only behind Jarmila Kratochvílová who ran 47.99 in 1983), and the third-fastest of all time. This had been her fifth race in five days and top five women all set PBs. She additionally took the bronze medal for the 4 × 400 m mixed relay, which set an Asian record. During 2019 Military World Games, the sprinter finished as the gold medallist in her signature event, extending her unbeaten streak in the event to 14 straight finals and a bronze one in the 4 × 100 m relay. Naser finished the 2019 season unbeaten.

### 2020–2022: Two year anti-doping regulations suspension

In June 2020, the Athletics Integrity Unit (AIU) issued a provisional suspension to Naser due to whereabouts failures over a 12-month period, including one filing failure and three missed tests. In October 2020, a World Athletics Disciplinary Tribunal dismissed the charges and lifted the suspension. However World Athletics and WADA appealed this decision to the Court of Arbitration for Sport (CAS). On 30 June 2021, CAS upheld the appeal, issuing a two year competition ban to Naser that ran from June 2021 to February 2023 (taking into account credit for the provisional suspension. All her results from 25 November 2019 to 30 June 2021 were also disqualified.

### 2023-present: Comeback and Olympic medallist

At the 2024 Summer Olympics, Naser won the silver medal in the women's 400 m final behind Marileidy Paulino. She clocked a time of 48.53 s, which was the second-fastest time of her career.
In November 2024, it was announced that Eid Naser had signed up for the inaugural season of the Michael Johnson founded Grand Slam Track.
