Around here (not worlds qualifiers) the GFNS events do timed climb segments. Not overall finish time. For Asheville and the other one. The 100 miler has 4 as the qualifier. So it is NOT a point to point race to the finish line. By all means, you could group ride/chat between the climbs quite slow if you're a competitive AG'er or overall contender.
Not sure what GFNS has to do with the UCI thing though.
