Great name for a century! Assuming the route remains similar, I'd say you should train with some 50 mile rides that have a climb like that at the end (looks like about 3k feet over 10 miles or so) because doing that climb when you're fresh is one thing, doing it after 50 miles... different. Except for that second climb at about 70 miles, which is much shorter, it looks like it's mostly downhill after that so the usual advice for riding a century applies.
