I like the concept of this Enduro type of races. I would rather see things evened out with a course where a longer travel bike and skills evened out the climbing though. Count the uphill and make it technical up down and across.
The cool thing about Enduro as it sits is the courses can vary quite a bit. Rather than a Downhill which is almost 100% gravity oriented, or XC which is majority fitness-based, or Super D which doesn't include an endurance aspect, Enduro includes elements of all of these.
While sanctioning Enduro may apply restrictions to events that want to be involved on that level, the discipline as a whole still has potential for different organizers to put their own twist on it.
I'm not really stoked on all-out XC racing, though I do like the endurance aspect of all day XC and AM rides so the prospect of more stage-based Enduro events locally is of great interest to me.
