Deep Earth Challenge

Would you like to take part in one of the toughest, most exciting and definitely unique running event in the World?


Deep Earth Challenge is a race that begins at the bottom of Europe’s deepest metal mine, Pyhäsalmi Mine. How deep is it? 1440 metres. Almost a kilometre and a half of vertical accent. The race travels up a service tunnel which is about 11 kilometres long making the average gradient 13%. It’s mostly gravel, it’s mostly dark and warm.

There will only be about 50 places. If you’d like to be one of them, please register here for interest.

…and science

We’re also taking this opportunity host the World’s deepest science talk. Why science? Good question. Pyhäsalmi Mine is shortlisted as the top contender for a very large, multi decade long EU science project, Laguna. There is already some heavy physics research taking place in the mine, think catching neutrinos flying through space from supernovas, and Laguna project would take this to a whole new level:

The FP7 Design Study LAGUNA is a collaborative project involving 21 European institutions. LAGUNA brings together on one hand the scientific community, and on the other hand the industrial and technical experts able to help assess the feasibility of this infrastructure.

New frontiers

  • The observatory will look for the unification of all elementary forces by searching for an extremely rare process called proton decay. Large size detectors like those envisioned in LAGUNA are the only way to address this question.
  • The large size of the LAGUNA observatory will, in addition, allow the detection of a sufficiently large number of neutrinos from very distant galactic supernovae to understand their explosion mechanism.
  • The observatory will also perform precision study of terrestrial, solar and atmospheric neutrinos.
  • Last but not least, the outstanding puzzle of the origin of the excess of matter over antimatter in the universe after the Big Bang, and the recent measurements of neutrino oscillations and masses, point forward to the need to couple the LAGUNA observatory to advanced neutrino beams from CERN to study matter-antimatter asymmetry in neutrino oscillations.
