On 3 August 2026 the ATP Challenger 100 tournament in Hagen, Germany and the ATP Challenger 75 tournament in Grodzisk Mazowiecki, Poland began their first day of competition. Qualifying rounds and opening main‑draw matches were scheduled on outdoor courts under heat alerts, with players such as Rudolf Molleker, Tim Handel, Juan Bautista Torres and Nikolai Barsukov in Hagen and Mirza Basic, Jiri Cizek, Ilya Ivashka and Oscar Weightman in Grodzisk Mazowiecki.

A few days later coverage shifted to the Mazovia Open ATP Challenger in Kozerki near Grodzisk Mazowiecki, running from 2 to 9 August. Backed by the Mazovian Marshal's Office, the event offered a €97.6 k prize pool and introduced a new VIP Silver covered stand, family zones, and an ELC Live line‑calling system with over 70 cameras. The draw featured former world No. 23 Damir Džumhur and Polish players Maks Kaśnikowski, Daniel Michalski, Tomasz Berkieta and Adam Majchrzak. Kaśnikowski was eliminated in the quarter‑finals, leaving Filip Pieczonka as the sole Polish player still competing, now in doubles with Morocco’s Younes Lalami Laaroussi. Rain caused a brief suspension of Kaśnikowski’s match against Spain’s Ivan Marrero Curbelo.
