Organizer\-advertised 2027 distance; approximate ascent converted from 8,189 ft\. Geometry not independently verified\. Density is derived from the same course’s total ascent divided by distance in kilometres, rounded to whole m/km. Nominal/approximate inputs produce approximate density. It is not gradient or a difficulty rating; missing, conflicting, bounded and aggregate metrics do not produce density. ## Practical information - Support: The organizer advertises stocked aid stations and on\-course mechanical support; riders should still be ready to self\-repair\. Outside assistance is restricted, with a Black\-course team\-feed exception at Hayden Gun Range\. Exact station counts and locations are not confirmed here: the course page and FAQ disagree on Red\-course counts\.
