Making Mining (and Marathon) History: Team Glencore Triumphs Underground

On 25 October 2025, 60 athletes from 17 countries descended more than a kilometre beneath the surface to take part in an extraordinary sporting challenge – the World’s Deepest Marathon.

Taking place 1,120 metres underground at Boliden’s Garpenberg Mine in Sweden, the event set a new Guinness World Record as the deepest marathon ever completed. Runners covered the full 42.2 kilometres through the mine’s illuminated tunnels, contending with mid-to high 20°C temperatures, high humidity, and the requirement to wear safety equipment throughout the race.

Representing Glencore, James Mason and Michael Pappas delivered outstanding performances, with James finishing in first place and teammate Michael taking home the bronze. Their achievements stand as a testament to the determination, discipline, and team spirit that define Glencore’s people around the world.

“Running 42 kilometres underground is not about speed, it is about mindset. And maybe a bit of madness,” said James.

“This wasn’t just a marathon. It was about showing the world a different side of mining – one that’s safe, responsible, and critical to advancing everyday life,” said Michael.

Beyond its sporting significance, the World’s Deepest Marathon offered a powerful reminder of how far the mining industry has come. The venue, Boliden’s Garpenberg Mine, which is widely considered to be one of the safest and most technologically advanced mines worldwide, highlighted modern mining’s commitment to innovation, safety and responsible production.

At Glencore, we are proud of James and Michael’s as well as all the other participants’ accomplishment and of the Values it represents. Their drive to go further – and deeper – reflects the same commitment our teams demonstrate every day as we responsibly source the commodities that advance everyday life.
