Ride or die question

I'm aware that you need to participate for 10 weeks in order to get the legion block, but what counts as participation? I accepted the quest on my new 236 Shade, and I started on difficulty A. I greatly underestimated this difficulty, as I'm very far away damage wise from being able to clear this horntail. Am I fucked in terms of participation this week, or will I still get rewards if I just clear the whole 30 minutes?
