.. allthough i think the conyers course is fairly tame...from what i hear anybody know anything on that?
Jonathen, before you do the race you need to watch the movie "24 Solo" with Chris Eatough. Talk about grown man crying in pain after a 24 hrs solo ride. I know you not doing it solo.. LOL.. but this will show you some preparation stuff, how the course was laid out and even show you the terrain in detail. "Short steep hills" is how Chris describes the course. Can't be more elevation then Dauset since they are within 20-30 miiles of each other. Most single track I saw on the movie was faily packed with little roots. There are scenes that show you roots and rocks. Tons of rock. Even pieces of trail over bed rocks. But that may be small sections. Check out the movie seriously.
If you can't get a hold of it Bob has a copy. Or you can find piece of it on YouTube. Actually, I just found one. Here is a link to it:
If I figure out how to post the video here directly I will shortly.
