Cyclocross - CX and SSCX races and training

Yes, you use the number for the entire series, then return it at the end.

The course isn't that hilly, I think @Chalfie is over egging it. It's normally based around the area above the lake, so some technical 180 degree bends on the slope, a section after that with tree roots, then a fast open bit around the grass between the lake and the road, then another technical section through the trees that sit inside the 180 turn that the road circuit uses, then a fast bit down to the area below Dead Man's corner, then there's usually a really tricky off camber series of 180 turns, then a steep hill, that is usually rideable, back up onto the road. This bit is usually rideable, but it's quicker to get off and run parts of it.
