It's unbelievable, but Arne Christensen is blind and with help from friend in front with a speaker in the backpack and one skiers behind him, did he manage to complete the world's toughest cross country race. Steep terrain with up or down is normal while straight ahead is the exception in the 160 km. Well done, I'm sure that you have inspired many people, not only the disables but every one - you have showed us that boundaries is in our head.
