Check out Trail Zombie's race report of Flatrocks 50K. He has some beautiful pictures of the trail. Double click on the pictures for a better view. You will get a clearer understanding of how rocky it really is. It wears me out just looking at them again.
I've just let Doug know if he wants to go back next year, I would pick up the costs. He likes that idea. It honestly makes me a little nervous. But...with the lessons I've learned and some of the things we've talked out and know we need to do different next time, I think it's doable.
