I am planning on the hill run in June and the century in July. If I am super fit and have lost weight, I will consider the hill climb in August. For me, it was brutally hard. I did walk the steepest mile in the middle, that made me sad. For that reason I'd like to take another shot at riding from bottom to top.
It's really easy to get in to the ride. I don't think they are selling out anymore, at least not for a couple of months. I know in the past it was hard to get in. The run is hard, it's a lottery system. I've gotten lucky for the last two years on the run.
