Mu turned pro in June 2021. After turning pro, she broke the US Olympic Trials record in the women's 800m and gave great media interviews. She then went to Tokyo, where she won gold in her individual event and chipped in with a 48.32 anchor leg for Team USA's winning 4x400m relay. After Tokyo, she traveled back to Eugene and fulfilled her obligation to Nike by running in the Prefontaine Classic and winning her race with a new American record. Then she made a public appearance in her hometown.
So, in just a few months of being a professional, Mu demonstrated the ability to:
- perform under pressure
- give great interviews
- be a team player for her country
- travel long distances
- make her sponsor happy
- engage fans
I think that's checking all the major boxes for being a professional track athlete beyond physical attributes.
The following year, Mu had an active competition schedule, racing in New York, Tempe, Austin, Philadelphia, Ponce, Rome, and Eugene. She won a Diamond League race, successfully defended her US title, then won World Championship gold while managing an injury to back up her Olympic victory.
That's plenty of evidence of Mu being cut out to be a professional track athlete.
The biggest challenge Mu faced was handling the expectations (both external and internal) of being an Olympic Champion at such a young age. She was expected to dominate and run blazing fast times, knowing that she would get skewered if she didn't. As they say, heavy is the head that wears the crown.
When people recount Mu's career on this board, one thing that often gets overlooked is how much change she navigated in such a short time at such a young age. Consider:
- spring 2020: covid disrupts her senior year of high school, and she missed out on major milestones such as prom and graduation. There's a lot of research that's been done on the adverse consequences covid disruptions had on the mental health of the class of 2020. Also remember that she did AAU track as a kid and didn't run for her high school track team. She missed out on a lot of normal things that high school kids usually get to enjoy.
- summer 2020: moves from New Jersey to Texas and starts freshman year at Texas A&M
- summer 2021: turns pro
- fall 2022: moves to LA to be coached by Kersee
- summer 2023 (est): breakup with Brandon Miller
That's a lot of transition for someone who only turned 21 in the summer of 2023. Normal college students would only be between their junior and senior years at that point!
Then she has the hamstring injury, the disaster at the 2024 Olympic Trials, etc. It was a lot. If we look at the full context of everything she's been through, it's no wonder why she'd want to take a break from the sport.
Still hoping she comes back better than ever to complete the arc of her track journey.
