Boliden mine to host world’s deepest marathon at 1,120m

July 17, 2025

The world’s deepest marathon will take part this October in an unprecedentedly challenging environment: 1,120 metres below sea level in one of Europe’s deepest mines.

The event, set inside Boliden’s Garpenberg zinc mine in Sweden, will see 60 amateur runners from around the world gather underground with the aim of breaking two world records and raise over £1 million ($1.34m) for charity. Mining.com
