Throughout his career, Malachowski faced several injuries. He underwent knee surgery in April 2020 and had a knee injury in early 2018 that halted his training for three weeks. In June 2017, he struggled with a back injury. He also had a hernia operation in September 2010 and injured his right shoulder during preparations for the 2008 season.
Since 2018, Malachowski has been training under Estonian discus thrower Gerd Kanter. Kanter, who won gold at the 2008 Olympic Games in Beijing, brought significant changes to Malachowski's training regimen. This included more intense training sessions and a structured warm-up routine.
Malachowski plans to retire after the 2020 Olympic Games in Tokyo. The Games were postponed due to the COVID-19 pandemic, but he chose to remain in the sport for an additional year. He aims to end his career at the Kamila Skolimowska Memorial meeting in September, where he plans for his son Henryk to throw a discus alongside him.
Post-retirement, Malachowski has expressed interest in working with manager Marcin Rosengarten. He completed a management course and was part of Rosengarten's organising team at the Kamila Skolimowska Memorial meeting in 2020. Additionally, he co-founded the sports clothing label Forever Stronger with fellow Polish athletes Konrad Bukowiecki, Pawel Fajdek, and Marcin Krukowski.
Malachowski resides in Biezun, Poland, with his wife Katarzyna and their son Henryk. He serves in the army and speaks Polish fluently. His nickname is "Machal," as noted in the NOC Media Guide of 2008.
In a notable act of generosity, Malachowski donated his silver medal from the 2016 Rio de Janeiro Olympics to raise funds for Olek Szymanski, a three-year-old child with retinoblastoma. This gesture enabled Olek to travel to the United States for treatment.
As Piotr Malachowski approaches retirement, his contributions to discus throw and his future plans reflect a commitment to both sport and community. His journey from a young talent discovered in Biezun to an Olympic medallist is inspiring for many aspiring athletes.
