Marisol Romero, a prominent figure in Mexican athletics, represented her country in two Olympic Games—London 2012 and Rio de Janeiro 2016—over a successful career spanning 19 years. In addition to her Olympic achievements, she also earned titles as a two-time champion at the Pan American Games in Guadalajara 2011 and as a champion at the Central American and Caribbean Games in Mayagüez 2010. Her impressive track record in long-distance running has made her a notable athlete in Mexico's sports history.

Following her retirement in 2023, Romero has shifted her focus from competitive sports to military service, taking on the role of Second Sergeant in Physical Education and Sports within the Secretariat of National Defense. She expresses a strong desire to learn more about military life and aims to advance her career within this new field. Romero's transition highlights the versatility of athletes, as many seek to apply their discipline and dedication in various pursuits after sports.

In addition to her military duties, Romero has embarked on a new venture by starting a running academy for children. This initiative underscores her commitment to nurturing the next generation of athletes, ensuring her legacy continues to impact the sporting world. Unfortunately, her experiences reflect a broader narrative of athletes struggling with retirement, as she points out the importance of maintaining a connection to the sport even after the competitive phase of their lives has ended.
