The biggest thing to realize for success at Ford/Ralph's, is not about the hill, it's about control. Your first 30 miles will be almost pancake flat! Then you will hit that hill, and 2 other sizeable hills after it, with plenty of rolling sections between them. If you go ridiculously for the first 25-30 miles, you're going to pay for it after the climbs. Last year I crossed 25 miles in under 1 hour, and ended up with a 2:28 bike split. Did I go out too fast? No! The 2nd half is just tough as hell, as a whole. Be quick, but controlled for the first half of the bike. Let it rip the second over the hills. That's my advice. You don't need to seek out any specific hills, you just need to do your training on all sorts of terrain, and learn to pace yourself well. Might be a good idea to do a ride that starts on flat and finishes with climbs and hills. Best of luck...
