That Hillside RR course is very difficult, but doable with the Cat 5's. I did that part of the course in the Heart of AZ Century, part of a 7k climbing day.
The Cat 5s in AZ usually have some decent climbers, so don't expect a walk in the park. That climb is going to hurt bad, and expect to get dropped, but that's just part of racing!
Make sure to give a wave to the ASU Cycling team, I think we'll have 5 or 6 guys in the 4s. Wish I could make it, but I graduated in the Spring and working now in South Carolina.
