Seems like the whole world is rounding on Challenge Budva for DQing Ditlev after cut the run short by 400m, he followed the lead bike, which made a wrong turn. He beat Lange by 8mins, so cutting the course made not materal difference.
I have massive sympathy for Ditlev, I am sure I would have done the same (not that I will ever be in that position). However, all the other athletes managed to run the right course, so I assume that it was correctly marked. A couple of times I have been on my own on the bike/run course, without the aid of a lead vehicle, and somehow manage to follow the course. I do feel that a DQ was harsh, maybe a time penalty would have been appropriate
