The EB is accessible. Many of us dream of doing the Tour Divide or some big stage race in British Columbia. However, those are generally just dreams like a super model (or super goat for some). The EB is like the cute girl next door who might be out of your league but occasionally gives you a smile. The EB is like a gateway drug to endurance mountain biking. At first you don't think you can do it, then you do it and fail or succeed, you find out if it's right for you. If only the ballers could do it, you'd end up with things like 1/2 marathons or 'EB light'.
I think that instead of making the EB harder, we need additional challenges. The EB used to seem crazy but now it feels more like a fun ride with the gang. The Dragon Slayer still seems crazy but it delivers a different kind of challenge. Maybe throw out an event called the "Grand Fijian" and do parts of the EB, parts of SATAN, and Brushy. Keep it around 100 miles, minimize road miles, and maximize fun.
