Su began her journey in Para athletics with aspirations to compete in the 2008 Paralympic Games in Beijing. However, she missed out on selection. This disappointment led her to leave the sport temporarily. In 2010, she discovered Para triathlon while browsing the internet. She convinced a friend to be her guide and borrowed a bike to enter her first race.

Achievements and Milestones

Su's dedication paid off when she became the first Spanish triathlete to win a Paralympic gold medal in the women's PTVI event at the 2020 Games in Tokyo. This victory was also Spain's first podium finish in a women's triathlon event at the Paralympic Games. She considers this gold medal her most memorable achievement.

Injuries and Challenges

Throughout her career, Su faced several injuries. In 2005, she sustained a knee injury and a femur bone marrow lesion, which kept her from training for three months. In 2023, she suffered an injury to the cuboid bone of her right foot but still managed to win a silver medal at the World Championships in Pontevedra, Spain.

Return to Para Athletics

Su returned to international Para athletics at the 2018 Grand Prix in Paris. She won a silver medal in the T11 1500m at the 2021 European Championships in Bydgoszcz, Poland. She also competed in the same event at the 2020 Paralympic Games in Tokyo alongside triathlon.

Awards and Recognition

Su has received numerous accolades for her contributions to sports. In 2023, she was named Female Para Triathlete of the Year by the Spanish Triathlon Federation. She received the Queen Letizia Award for Spanish Female Athlete of the Year for 2022, becoming the first Para athlete to receive this honour.

Heart Condition and Medical Career

In January 2020, Su was diagnosed with long QT syndrome, a heart rhythm disorder. She underwent surgery to implant a heart monitor that sends heartbeat data to a hospital in Vigo. This allows immediate detection of any anomalies. Despite this condition, she continues to push hard in training sessions.

Alongside her athletic career, Su works as a medical specialist in physical medicine and rehabilitation in Vigo. She believes that both medicine and sport require perseverance and continuous improvement.

Club Founder and Inclusivity Advocate

In 2021, Su co-founded the Delikia sports club in Vigo with Celso Comesana Pereira. The club focuses on inclusivity, and Su serves as its honorary president.

Future Ambitions

Looking ahead, Su aims to compete at the 2024 Paralympic Games in Paris. She has decided to focus solely on triathlon for these Games as it brings her the most joy.

Personal Interests and Philosophy

Outside of sports and medicine, Su enjoys travelling, spending time outdoors, and listening to music. Her personal philosophy is: "There is only one way to get things done and that is to not be afraid to fight."

Role Model Recognition

In 2024, toy company Mattel launched a Barbie doll with Su's likeness as part of its Barbie Role Models campaign. Su expressed that having a Barbie doll modelled after her is an example of achieving childhood dreams through hard work.

Su's journey from missing out on the Beijing Paralympics selection to becoming a Paralympic gold medallist is inspiring. Her story highlights resilience, dedication, and passion for both sports and medicine.
