Mpumi has faced several injuries throughout his career. He developed patellar tendinitis while in high school, which prevented him from competing in European competitions in early 2016. In 2023, he sustained injuries to his back and knee. He was also recovering from a hamstring tear ahead of the 2024 Paralympic Games.
Mpumi is married to Monique and enjoys reading, travelling with his wife, playing football, padel, and cycling. He speaks multiple languages, including Afrikaans, English, French, Portuguese, Xhosa, and Zulu. His younger brother Asane has also competed in sprinting.
In 2019, Mpumi launched the #SomeoneWhoCares campaign to raise awareness about challenges faced by people living with impairments. He believes that through his successes as a Para athlete and advocacy efforts, a global spotlight can be shone on these issues.
In addition to his athletic and advocacy work, Mpumi co-founded a digital healthcare company called Steady State in 2018. The company aims to provide simple solutions to improve public healthcare and save lives.
Looking ahead, Mpumi aims to win gold and set a world record at the 2024 Paralympic Games in Paris. His dedication to training is evident as he trains for up to six hours a day. Inspired by South African Para sprinter Ntando Mahlangu and influenced by his mother, Mpumi lives by the philosophy: "To be great means to enjoy what you do a little more every day."
Mpumi's journey is a testament to his resilience and determination. His contributions extend beyond sports into advocacy and business, making him a multifaceted individual committed to making a difference.
