I'm just a slow bike chick but did manage to run on all 3 course during speed week. The left most long course I thought was crap the last day. I was extremely thankful to be on a very stable proven bike. It reminded me of dirt bike riding from the 3 to 4. Lots of wheel spin & bumpy. I had an unintentional shut down as I came past the 4 MM so I only coasted through the 5 lookin to turn off. (probably a blessing) I managed to qualify on my first run on that track but was more excited that I got off the track without incident then I was that I qualified.
I ran again since I was trying to back it up & stayed extreme right which seemed a bit better/less wheel spin but still not solid per say.
The short course was wonderful the first day. Hard and flat. The combo course was good the 2nd but maybe not as nice as the short course. I rode the short course again in a car for orientation on the 3rd day & it was starting to get bumpy.
It seemed to me like the courses were pristine at the start but that was the best of it. Of course the head winds didn't do any of us any favors either!
