In a remarkable display of endurance, grit, and courage, a group of 57 runners from around the globe descended 1,120 meters underground to take part in the world’s deepest marathon — a historic event held in the Garpenberg Zinc Mine in Sweden.
Organised by BecomingX in partnership with the International Council for Mining and Metals (ICMM), the “World’s Deepest Marathon” challenged participants to complete 11 laps around a subterranean route to cover the full 42.2 kmdistance.
The event is now poised to set two Guinness World Records — one for The Deepest Marathon and another for The Deepest Underground Marathon Distance Run (Team) — while raising funds for two charitable causes: the BecomingX Foundation and the Wild at Heart Foundation.
South Africa’s Representation Underground
Among the participants was Ledile Dikgale, Mining Section Manager at Kumba Iron Ore, who proudly represented South Africa and the Anglo American family in this groundbreaking challenge.
Reflecting on the experience, Dikgale described the marathon as both physically demanding and deeply rewarding.
“This is one of the most important achievements of my life — I am truly proud and exhilarated! It was a once-in-a-lifetime opportunity to be part of a historic event, and to do it while raising funds for charity made it even more meaningful,” she said.
Dikgale explained that she was nominated by Kumba’s Executive Leadership to run on behalf of CEO Mpumi Zikalala, an honour she embraced wholeheartedly.
“With the support of my running community, I completed training runs in the dark to prepare for the underground conditions. I also had to acclimatise to the heat by running in the afternoons, simulating the temperatures we would face below the surface,” she added.
She expressed her gratitude to the Kumba Executive Leadership team, her family, friends, and running community for their support and encouragement throughout her journey.
A Testament to Courage and Grit
Kumba Iron Ore CEO Mpumi Zikalala praised Dikgale’s remarkable achievement, describing it as an embodiment of the resilience and spirit that define Kumba’s people.
“Ledile’s achievement is a powerful reminder of the courage and grit that define our people at Kumba and is testament to the incredible potential within our teams,” said Zikalala.
“Running a marathon more than a kilometre underground is extraordinary on its own, but doing so in support of a greater purpose makes it even more meaningful. We are incredibly proud of her for representing our business and our country with such heart, discipline, and determination.”
About the World’s Deepest Marathon
The event — hosted in one of Europe’s oldest active mines — pushed the boundaries of human endurance, testing athletes in conditions of limited light, high humidity, and elevated temperatures. Beyond the physical challenge, the marathon highlighted the commitment of the global mining community to teamwork, resilience, and purpose-driven initiatives.
