Mia Maxwell is an American track athlete who competes in sprint events and the triple jump. Her career reached a new level at the 2026 World Athletics U20 Championships, where she won the women’s 100 meters in 11.14 seconds before completing the sprint double with a personal-best 22.37 in the 200 meters.
Those victories followed a rapid progression through Texas high-school competition, national championships and senior-level indoor racing. Maxwell had already set a UIL Class 6A state-meet record in the 100 meters, won state and national titles, and finished second against senior athletes at the 2026 USATF Indoor Championships.

Texas Sprinting and Triple Jump Built Maxwell’s Foundation
Maxwell attended Atascocita High School in Humble, Texas. She has said that she and her twin sister, Mariah, began pursuing track in eighth grade. Their preteen attempt at track in Indiana was short-lived; serious participation began only after the family moved to Texas.
Her development was not limited to one discipline. Maxwell competed in both the sprints and triple jump, giving her a broader athletic program than many short-distance specialists.
That versatility was evident at the 2025 UIL Class 6A state championships. She won the triple jump with a mark of 42 feet, 2¼ inches and then captured the 100 meters in 11.04 seconds. The UIL record book lists that sprint performance as the Class 6A state-meet record.
The precise classification is important. Although some reports described the performance more broadly as a Texas state record, the official UIL record supports calling it the Class 6A state-meet record. Humble ISD also published an inaccurate description saying Maxwell had broken a 17-year-old record by “12-tenths” of a second. The UIL record book lists the previous mark as Jasmine Montgomery’s 11.09 from the 2020–21 season, making Maxwell’s improvement 0.05 seconds.
She also helped Atascocita finish second in the 4×100-meter relay at the same state meet. Gatorade recognized Maxwell’s season by naming her the 2024–25 Texas Girls Track & Field Player of the Year.
APXP Training Strengthened Her Technical Development
Maxwell and her sister began working with coach Danny McCray’s APXP Performance group after their sophomore season in May 2024. At that stage, Mia was rehabilitating an injury and concentrating on returning to health while improving her mechanics. The injury itself was not publicly identified.
Maxwell told Track & Field News that working with McCray gave her a stronger technical understanding of sprinting. She said the coaching covered the technical side of running as well as habits involving nutrition and physical treatment. Before joining the group, she felt she had been running without fully understanding the mechanics behind her performances.
A missed state qualification during her sophomore season became part of that transition. Maxwell recalled falling narrowly short before McCray told her it would not happen again. Her results improved sharply after the move to more specialized training.
Following the 2025 season, Mia and Mariah decided not to represent Atascocita in competition during their senior year, although they remained students at the school. Maxwell described it as a difficult choice because of her relationships with the team and coaches. She said the sisters wanted greater control over their event programs, including more opportunities for Mia to race the 200 meters and Mariah to contest the 100.
National Results Prepared Maxwell for Senior Competition
Maxwell carried her Texas success into national competition during 2025. She won the 100 meters at Nike Outdoor Nationals and later captured the USATF U20 200-meter championship in 23.10 seconds.
At the time, 23.10 was reported as her personal best. Her later World U20 performance reduced that figure considerably, so the 2025 time is best understood as a marker of where she stood before her next breakthrough.
Her jumping remained an important part of her competitive identity. During a December 2025 jumps showcase, she produced a major triple-jump performance while trying to establish herself as more than a sprinter. The jump appeared under two imperial measurements in published coverage—44-6 in one report and 44-5¾ in another. The performance itself was significant, but the differing imperial figures make the exact measurement unsuitable without the official meet result.
Maxwell explained that she wanted people to recognize her ability in the triple jump. Her work with jumps coach Marlin Hargrove had begun well before her national sprinting success, and she continued balancing the two disciplines as her profile grew.
A 7.13 Indoor Performance Confirmed Her Senior-Level Speed
The 2026 indoor season placed Maxwell against experienced senior competitors. At the USATF Indoor Championships on March 1, she advanced to the women’s 60-meter final and finished second behind Jacious Sears.
According to Track & Field News, her 7.13-second finish matched the existing US high school record. Mariah followed in third place with 7.14, putting the sisters side by side on the senior national podium.
Mia later said the significance of the result took time to register. Sharing the moment with Mariah made it more memorable, particularly because their development had not followed the same path.
The finish gave Maxwell an important senior-level result before the main outdoor championship season. She had not won the national title, but she had competed successfully against senior athletes while still in high school.
Competing With Mariah Remained Supportive as Well as Competitive
Mia and Mariah often entered the same sprint events, creating a competitive dynamic that drew attention as their results improved. Mia rejected the idea that racing her twin was especially difficult. At a World Athletics press conference, she explained that they approached the start line as individual athletes who both wanted to win.
That competitive approach did not remove their support for one another. Maxwell said they would remain present for each other regardless of how a race finished.
She also spoke openly about the possibility that their athletic paths would eventually separate. Rather than treating that prospect as a negative development, she described it as a natural and positive part of their growth. No confirmed information indicated that they would attend the same university or make identical career decisions.
Their progress also shaped the advice Mia offered younger athletes. She encouraged them to trust the process, recalling that the twins’ serious involvement in track didn’t begin until eighth grade. Reaching a world-championship press conference was not something she had expected when they started.
The 100m Victory Delivered Her First World U20 Title.
The sisters qualified for the 2026 World Athletics U20 Championships after finishing first and second in both the 100m and 200m at the US U20 Championships. At the global event in Eugene, they advanced through the early rounds of the 100 meters, with Mia recording the fastest semifinal time at 11.13 seconds.
The final pitted Maxwell against Jamaica’s Shanoya Douglas, whom World Athletics identified as the world U20 leader. Mia won the race in 11.14 seconds, securing her first global age-group championship.
Her August 6, 2026 victory marked another step beyond her national results. She had entered the season with a Texas state-meet record, national high-school titles and a senior US indoor podium finish. She now held a World U20 title in one of track’s central sprint events.
The 11.14 winning time was not her personal best. Her 11.04 from the 2025 Texas state meet remained the fastest performance documented in her record, but the championship final delivered her most important 100-meter victory.
A Personal Best Completed the World U20 Sprint Double
Maxwell returned to competition two days later for the women’s 200-meter final. This time, she combined the championship result with a substantial improvement on her previous best.
She won in 22.37 seconds, completing the 100m and 200m double at the same World U20 Championships. World Athletics reported that she became the fifth woman to achieve that combination in a single edition of the event.
The performance lowered her 23.10 personal best from her 2025 USATF U20 title. It also completed a progression central to her decision to pursue a more flexible senior-year competition schedule. After seeking more opportunities in the 200 meters, she finished her U20 career as the world champion in both short sprints.
The titles were World U20 championships, not senior global titles. Even so, they added international results to a record that already included success in high school, U20 and senior national competition.
The University of Texas Is Her Confirmed Next Step
During the World U20 Championships, Maxwell publicly confirmed her commitment to the University of Texas. She framed the decision around continued development rather than an immediate move into professional competition.
Maxwell said she believed she still needed to learn and gain experience in college. She also said she wanted to succeed at the collegiate level before considering the next stage of her career.
The commitment identifies her intended direction after high school. It does not, by itself, confirm that she has enrolled, joined the official roster, or competed for the university.
Her high-school record also included work outside athletics. Gatorade reported that she held a 3.83 GPA during the 2024–25 school year, played viola in the Atascocita orchestra and volunteered through Humble ISD’s Fill the Bus project. Those details describe her activities during that period, not her current university status.
Maxwell’s Versatility Shaped Her Rise to Two World Titles
Maxwell’s progression combined sprinting, triple jump, and increasingly specialized technical training. She moved from narrowly missing state qualification as a sophomore to setting the UIL Class 6A state-meet 100m record, winning a state triple-jump title and collecting national championships.
Her 7.13 runner-up finish at the 2026 USATF Indoor Championships showed she could contend with senior athletes. Five months later, she won the World U20 100 meters and lowered her 200-meter best to 22.37 while completing the championship double.
The University of Texas commitment provides the next documented step in her development. At the end of her U20 period, her record included elite results across two sprint distances, national-level indoor competition, and sustained involvement in the triple jump.
