Bloemfontein-based chartered accountant at Forvis Mazars South Africa, dedicated family man, and accomplished endurance athlete, Thinus de Vries is a compelling example of how discipline and purpose can shape success across every area of life.
Balancing a demanding professional career with elite-level marathon running and family responsibilities, he continues to pursue excellence with intention. Most recently, De Vries completed the 130th Boston Marathon in April 2026 in an impressive time of 2:45:18.
He has also earned the Abbott World Marathon Majors Six Star medal, a prestigious award given to runners who have completed all six of the original major marathons that took place in Tokyo, Boston, London, Berlin, Chicago, and New York City. With his completion of the New York City Marathon in November 2025, he achieved this milestone on the same day as the legendary Eliud Kipchoge.
De Vries’ journey began in 2018, when he decided to leave behind his unhealthy lifestyle. “I’ve always had a history of being active and fit, but during my studies and at the start of my professional career, I completely stopped exercising and began living unhealthily,” he says openly.
“By January 2018, I weighed 112 kg. I realised this lifestyle was neither sustainable nor healthy. I knew I wasn’t living as the best version of myself.”
What started as a personal turning point soon became a structured pursuit of balance. “I began cycling to get my body used to movement again, and with healthier eating habits and consistent training, I slowly but surely started making progress,” he explains.
“I developed more energy, greater focus, and a deeper appreciation for balance between work, health, and family.”
That same discipline carries into his professional life. “Consistency and discipline are the foundation of success for me – not only in sport, but also in my professional life,” he says. “I am very strict with my training programme and make sure every session is written into my diary, just like any other important appointment with a client or colleague.”
Family remains central to his journey. “My wife, boy and parents deserve special recognition because they regularly hear about my fatigue and muscle pain … The prayers of my family carry me every day.”
Reflecting on his achievements, he says the medals are reminders to him that it is possible to dream big. “The journey there (to reach for your goals) holds just as much value as the finish line itself.”
