Mark Plaatjes

A native of South Africa, Mark Plaatjes was one of the world’s best marathoners in the 1980s, but he couldn’t compete internationally because of the boycott against the country’s apartheid policies. He sought political asylum in the U.S. in 1988 and eventually moved to Boulder to train with some of the world’s best runners and work as a physical therapist. On Aug. 14, 1993, just three weeks after he became a U.S. citizen, Plaatjes won the marathon (2:13:57) at the World Championships in Stuttgart, Germany. Plaatjes, who owns a 2:08:58 marathon PR, is the owner of In Motion Running, which he opened in November 2018. Mark was inducted into the Colorado Running Hall of Fame in 2008. (Photo: Mark Doolittle)
