Hindustan Zinc has announced the successful completion of the World’s Deepest Marathon, setting two new Guinness World Records at Boliden’s Garpenberg zinc mine in Sweden. The event marks a historic achievement for the global mining sector and reinforces the company’s leadership in safety, innovation and endurance.

Fifty-seven runners from 18 countries, including Hindustan Zinc’s Chief Executive Officer Arun Misra and Chief Operating Officer Kishore Kumar S., participated in the underground marathon held 1,120 metres below sea level. The initiative has set records for The Deepest Marathon (Individual) and The Deepest Underground Marathon Distance Run (Team), making Arun Misra the first Indian to be recognised in these categories.

Conducted on 23 October 2025 and organised by BecomingX, Boliden and ICMM, with Hindustan Zinc as the only Indian Official Partner, the event showcased advanced mining environments and operational safety. Participants completed 11 laps of a 3.84 km tunnel under extreme conditions including high humidity, temperatures of up to 30°C, gravel terrain and minimal light, raising more than US$1 million for the BecomingX Foundation and Wild at Heart Foundation.

Arun Misra, CEO, Hindustan Zinc, said, “Participating in the World’s Deepest Marathon was not just an endurance challenge but was a powerful symbol of how the mining industry has evolved. Glad that we at Hindustan Zinc were able to partner in this record-breaking event organised by BecomingX, Boliden, and ICMM. The World’s Deepest Marathon showcased that with safety, technology, and collaboration, we can achieve extraordinary feats even in the world’s most challenging environments.”

Paul Gurney, CEO, BecomingX, stated, “The World’s Deepest Marathon is a powerful demonstration of what we can achieve when we dare to go beyond the ordinary. Completing this event, and setting not one but two world records, captures the true spirit of adventure and resilience that BecomingX stands for.”

Rohitesh Dhawan, CEO, ICMM, said, “To host a full marathon underground safely and successfully is a remarkable achievement, and a true testament to the transformation of the mining industry.”

Hindustan Zinc’s involvement underscores its focus on sustainable mining, fitness and community enrichment, also reflected in initiatives such as the Vedanta Zinc City Half Marathon and grassroots programmes including the Zinc Football Academy and the AIFF Zinc Blue Cubs League.

The company emphasised that global partnerships will continue to drive innovation, safety and progress across the mining sector.
