Heh, I know the guy in the brochure, who will be leading the rides. He is one strong dude (former SOS triathlon winner). Plus the Mountain House is, you know, on top of a mountain, meaning you get a seriously uphill finish (like a hard category 2 climb). Probably they will shuttle riders down/up the hill for the ride, at least for the B/C rides.
It looks like a great event, and you can't beat the resort for a recovery setting! This is a spectacular area for biking in the hills.
