There are sunsets in Kozerki that look almost like ready-made posters. This year, they became the inspiration for the official artwork of the Mazovia Open ATP Challenger 2026.
Here is the poster for this year's edition of the tournament—drawn from the colors of Kozerki’s unique sunsets and the atmosphere of the courts, where in August we will once again witness international-level tennis.
The Mazovia Open ATP Challenger 2026 will take place from August 2–9, 2026 in Kozerki, near Grodzisk Mazowiecki. Ahead of us is a week of sporting excitement, intense rallies, a battle for ATP ranking points, and the chance to meet players you’ll want to see up close.
This is another edition of the tournament previously known as Kozerki Open. In 2026, the event is held under the name Mazovia Open ATP Challenger, highlighting the tournament’s connection to Mazovia and its growing presence on the international tennis map.
The best proof that you can watch tennis with great potential in Kozerki? Last year, Kamil Majchrzak won the tournament. Stories like this remind us that on the Challenger courts, you can witness play that continues far beyond the tournament’s final point.
But this year’s edition is about more than just on-court competition. Mazovia Open ATP Challenger 2026 will also be a space for meeting, cheering together, and enjoying summer in Kozerki. There will be zones for the whole family, activities, shows, additional attractions, food options, and—for the first time—the Sport & Business Zone, a space for conversations, networking, talks, and building unique relationships.
We invite fans, families, business partners, sponsors, and media to take part in the event. Mazovia Open ATP Challenger is a week where sport, business, Mazovia, and the unique atmosphere of Kozerki come together in one place.
