Perhaps for the first time in international event it's possible to choose to run on a map without footpaths or tracks. Organizers decided to make the challenging terrain even more difficult for those who look for more contour reading fun! To attract more entries in "Ultimate classes" organizers offer promotional fees and a free T-shirt for everyone completing the whole 5 days.
Brilliant, I ran off the map on the first day a couple of years ago with paths!
