Błachowicz is a close friend of former UFC fighter Tomasz Drwal. They were training together at the Throwdown Training Center in San Diego when he suffered his knee injury in 2009. Some time ago he moved to Warsaw with his girlfriend, changing his long-time club Octagon Rybnik to Paweł Nastula's club. He also occasionally trains in Alliance MMA with names such as Alexander Gustafsson, Phil Davis, Joey Beltran, and Dominick Cruz.

Despite suffering a serious knee injury in July, Błachowicz continued his training, as he agreed to fight "somewhere in Mexico". About three weeks later, his knee suddenly popped in training when executing a takedown. The anterior cruciate ligament in his right knee was destroyed, making a knee reconstruction after his return to Poland inevitable.
