Here is everything you need to know about how Athing Mu shot to prominence despite her tender age.

At just 22, Athing Mu has already acquired superstar status with her unmatched achievements and heroics on the track.

Born on June 8, 2002 in Trenton, New Jersey, Mu started running track at age 6, justifying why she wanted to curve her own path in athletics with passion.

Pulse Sports reveals the details regarding how Mu's formative years was crucial in shaping her 800m career.

Athing Mu attended Trenton Central High School, but joined the Trenton Track Club instead of the high school track team. Her choice of where best she could be molded perhaps was integral in her meteoric rise.

Her story is not for the faint-hearted. Athing Mu is the second youngest of seven siblings. Her parents immigrated to the United States from South Sudan, and her family is of South Sudanese heritage.

Graduating from Trenton Central High School in 2020 offered Mu the lifetime opportunity to show to the world what she was capable of. This set the tone for a four-year of absolute dominance, sweeping away opponents whenever she raced.

Collegiate record

Mu broke the American women's record at the 600-meter event at the 2019 USA Indoor Track and Field Championships with a time of 1:23.57, besting the previous American women's record of 1:23.59 held by Alysia Montaño, and nearly broke the women's world record of 1:23.44, held by Olga Kotlyarova. Never mind that Mu was only 17

Athing Mu ran 1:58.40 in the 800m to set an indoor collegiate and world under-20 record. She bested the previous collegiate record by more than two seconds.

Tokyo Olympic dominance

Mu qualified for the delayed 2020 Tokyo Olympics at the US Olympic trials held in Eugene, Oregon by placing first in the event with a time of 1:56.07, a world-leading time and the second-fastest result in American history.

At the Tokyo Games, she won two gold medals for the women's 800m and 4x400 meters relay.

In her individual event, Mu led from gun to tape in a dominant showing, finishing clear ahead of Keely Hodgkinson and compatriot Raevyn Rogers. She broke the American women's 800 meter record with a 1m 55.21s performance and ended a 53-year Olympic win drought for the USA.

The last American woman who won the event was Madeline Manning at the 1968 Mexico Olympics (first Olympic 800m male or female win since Dave Wottle at the Munich 1972). Mu became also the youngest U.S. woman to win individual Olympic track and field title since Wyomia Tyus earned the 100 m title at the 1964 Tokyo Games.

After claiming Olympic gold in Tokyo at age 19, the New Jersey native Mu made a major move: She packed her bags and headed to Los Angeles, to train with famed coach Bobby Kersee - alongside the likes of fellow Olympic champion Sydney McLaughlin-Levrone.

Mu has previously said Kersee is the best coach she's worked with and his father-figure approach, makes interaction during training session normal.

Crazy winning record

In her first post-Olympic race at the Prefontaine Classic, she set even better American 800m record of one minute 55.04 seconds despite running by herself over the final lap, also the all-comers' record, making her the second fastest U20 woman ever after Pamela Jelimo and putting her eighth on the world all-time list.

In that record-breaking season Mu competed 36 times (including rounds) and triumphed in 35 races to be voted World Athletics Female Rising Star of the Year.

At the 2022 World Championships in Eugene, Oregon in July, Mu this time barely held off Hodgkinson to take the women's 800m gold with a world-leading time of 1:56.30.

She won by 0.08 s after a tight finish on the home stretch, with Mary Moraa trailing in third. Thus, Mu became the first American woman to win the 800 m world championship title, and the youngest woman in history to own Olympic and world titles in an individual track and field event.

At September's 2023 Prefontaine Classic, she won the Diamond League final in a time of 1:54.97 to set an American record and defeat Moraa and Hodgkinson.

Mu failed to defend her Olympic title last year after she failed to qualify during the USA trials. She will be looking to redeem herself in 2025, and pick up from where she left in a bid to return to her ruthless nature.
