Career
He swam for Poland at the 2007 World Championships in Melbourne, Australia in the 100 m and 200 m breaststrokes. He did not advance out of the preliminaries in either, finishing 29th in the 100 and 17th in the 200—just missing advancing in the 200 by 0.04 seconds. Wolniak set the Polish Records in the 50m, 100, and 200m breaststrokes at the 2009 Polish Nationals (50m) in Ostrowiec Świętokrzyski, Poland, May 21–24.
Ironically, Wolniak"s record-setting effort in the 50 breast, came in the consolation final, as he failed to qualify for the “A” final.
