I hiked over Beat Mountain once when doing some section hiking on the Appalachian Trail. Part of the AT is actually on Perkins Road (IIRC) which I think is the main biking road. There was one dude riding it who looked pretty strong. I gave him a good "Vengavengavenga!".
Since then I've been thinking of making a little personal century out of riding up there and back (including the climb, duh). I'd love to know the "stats" so I could get an idea of how tough it is compared to, say, "Alpine d'Huez".
