Registration is open for the Swank 65 on Active.com.  The race is a 65k (42 mile) romp through the Pisgah National Forest on a combo of mining roads, singletrack, monster climbs and “hell raising” descents.

Todd Branham, race promoter, also puts on the ORAMM (Off Road Assault on Mt. Mitchell) every year.  I’ve participated in that event once and will say that it was well organized with great post-race burritos and drinks.  Get more info on this event here.
