"On October 25th 2025, 55 intrepid runners took on an extraordinary challenge: to run the deepest marathon ever run. Covering 42.2km within the Garpenberg Zinc Mine in Sweden, they descended to a staggering depth of 1,120 metres below sea level. No one had attempted a marathon at this depth before. Participants endured temperatures of 24°C and 72% humidity, in total silence and ran in complete darkness with only their head torches for light."
it was organized by a mining company to showcase modern mining safety and environmental standards
That's pretty creative
Badass
So can you run a better time because you get more oxygen with each breath?
I guess the 24°C is a bit warm for a marathon, but assuming that temperature was not a limiting factor?
Heavy assumption for a distance race
I had to go look up more informarion (link)
but it sounds like the stagnant air in the mineshaft would actually naturally inhibit running. They had to actively pump in fresh air from the surface down to the mineshaft during the marathon
All the mines around here do that for the workers anyway.
