We do not know the details.My understanding is that the check was poorly marked.Enough so that most of the top first riders through the section missed it.These are world class offroad pros.At some point the section was sorted out for subsequent riders.
If the Oz trophy team made it through the section without problems before changes were made.Then they can whine some, if that's how they want to be remembered.If the section was sorted out before they came through, which I believe is the case.
Then they got beat and really I have no respect for a team who wants to win by default or by the misfortunes of others.
Typical in this day .
