I don't think the course at NXR will save Niwot, CMHS outclassed them at state last year, and the RLN results seemed very similar last year. I don't think there was evidence last year to indicate that Niwot performed worse on the hilly course. Addtionally, I think there is about 400-600m where the narrowness is an issue, from the bridge to the mile mark. Little Willis seperates the men from the boys and there is plenty of room to pass after that.
