Marta Kostyuk, a prominent Ukrainian tennis player, has been training in Kyiv amidst air raid sirens, reflecting the ongoing realities of the war in Ukraine that has persisted for over three years. After a strong start to her 2026 season, reaching the final of the Brisbane International, Kostyuk faced disappointing early exits in major tournaments including the Australian Open, Indian Wells, and the Miami Open. Despite these challenges, she remains dedicated to her training and has returned to Kyiv to prepare for the upcoming clay season. Kostyuk, who has won three WTA titles, dedicated her maiden title to the people of Ukraine, emphasizing the emotional weight of her achievements during such difficult times. She has been an outspoken critic of allowing Russian and Belarusian players to compete on the tour, urging them to condemn the war. Kostyuk's commitment to her country is also evident from her participation in the Paris Olympics, where she represented Ukraine with fellow player Dayana Yastremska.
