Going underground

People come up with the creasiest places tot run (a marathon). In Germany they ran a marathon last week in a former saltmine. The Kristallmarathon in Merkers:

• 500 meters underground;
• 13 laps;
• 750m climbing;
• 500 participants;
• Helmet and headlight mandatory;

The winner finished in 2:45. The mine is used for other activities such as mountain biking (or should I say underneath mountain biking) and various concerts.

Below some video's to give you an impression of the event.
