A couple interesting, early-season happenings in Virginia. Don't shoot me, but, I'm hoping there's still snow in Michaux in early April :)
A 13-Hour race not too far south of here (Leesburg, VA)
The sponsor's site here.
CycleFest Duathlon (Fairfax, VA)
I know a few MBM folks have ridden this place (Wakefield Park). And I can certainly vouch for the high grin factor there, especially, with all the new IMBA-built bermed singletrack and rollers. Similar to the Marysville courses.
