Maria Andrejczyk, a prominent Polish athlete, has made significant strides in the sport of javelin throwing. Born in Suwalki, Poland, she began her athletic journey in primary school in Sejny. Initially involved in volleyball, she shifted her focus to javelin throwing two years later. Her talent was recognised by coach Karol Sikorski, who encouraged her to pursue the sport seriously.

She has also been honoured with the Newcomer of the Year award at the 2016 Polish Sports Personality of the Year Awards. This recognition highlights her rapid rise in the sport and her potential for future success.
Throughout her career, Andrejczyk has faced several injuries. In early 2015, she dealt with an elbow injury. She underwent right shoulder surgery in December 2016, causing her to miss the 2017 season. In October 2019, a sinus x-ray revealed an osteoma, a benign bone tumour, which required surgery.
In January 2020, she struggled with ankle and Achilles tendon injuries and underwent surgery in March that year. Despite these setbacks, Andrejczyk remained resilient and continued to train hard.
Andrejczyk resides in Suwalki with her partner Marcin Rosengarten, who also serves as her manager. She speaks multiple languages, including English, French, Polish, and Russian. She pursued higher education in English and Russian language studies at the State Higher Vocational School in Suwalki.
Her hobbies include drawing, reading books, architecture, and listening to music. These interests provide a balance to her rigorous training schedule and contribute to her overall well-being.
Looking ahead, Andrejczyk aims to win a medal at the Tokyo Olympic Games. The postponement of the Games due to global events has given her additional time to prepare and recover from injuries. She views this delay as an opportunity to be better prepared for competition.
Andrejczyk draws inspiration from Czech javelin thrower Jan Zelezny and Polish javelin thrower Barbara Madejczyk. Her sporting philosophy is encapsulated in her motto: "As long as you fight you are a winner." This mindset has helped her overcome numerous challenges throughout her career.
Her partner Marcin Rosengarten has been a significant support system for Andrejczyk. He was part of the coaching team for the Polish handball squad at the 2016 Olympic Games in Rio de Janeiro. Additionally, her younger brother Adam competes in javelin at the junior national level in Poland.
Maria Andrejczyk's journey is marked by perseverance and determination. From early beginnings in Sejny to competing on the world stage, she continues to strive for excellence. With Tokyo on the horizon, she remains focused on achieving her dreams and making Poland proud.
