Maria's career has been marked by numerous accolades. In 2005, she was named Sportswoman of the Year by the newspaper El Espectador. This recognition came after her notable performance at the 2004 Olympics.
However, her journey has not been without challenges. After the 2004 Olympics, she tested positive for heptaminol, leading to the temporary stripping of her medal. Maria had taken a headache pill called Neo-Saldina before her race. She appealed the decision, and a Switzerland-based court upheld her appeal. The court found that isometheptene, present in the pills, was not on the banned substances list for the Games. Consequently, her medal was returned to her.
Maria has been under the guidance of coach Jose Julian Velasques since 2011. She trains with the Indeportes Government of Antioquia team in Colombia. Her dedication to training is evident despite facing setbacks like the accident in Antioquia where she hit a drunk pedestrian while training.
Away from cycling, Maria enjoys spending time with dogs. This hobby provides a balance to her rigorous training schedule and competitive career.
Looking ahead, Maria aims to continue competing at high levels and possibly take on mentoring roles for upcoming cyclists in Colombia. Her experience and resilience make her a valuable asset to the sport.
Maria Luis Calle Williams' journey is a testament to her perseverance and dedication to cycling. Her achievements have paved the way for future generations of Colombian cyclists.
