Heidi began her sporting journey with athletics and netball. She discovered adventure racing through her partner — now her husband — Stephan Muller. Her passion for the sport turned into a full-time career with the creation of Expedition Africa.
For the past 15 years, she has devoted herself wholeheartedly to developing adventure racing in South Africa, organizing multiple events each year. In October 2023, Heidi hosted the Adventure Racing World Championship in South Africa before starting a new chapter in Australia with her family. She now dedicates all her energy to growing the Adventure Racing World Series (ARWS).
As CEO of the ARWS, she balances her work, with organizing multicultural meetings across different the time zones of the globe, all while being a mother of three.
Heidi’s superpower is her ability to bring people together, recognize their skills, and unite their efforts.
