Go to www.ironbutt.com and read their tips for long-distance riding. They specialize in endurance riding, and the tips they give on how to prepare and strategies to make a long trip work will be very useful. If you've never taken a long trip, there's probably a lot you haven't considered, and 2240 miles in 4 days is probably not realistic -- you'll beat yourself to death. Figure more like 6 days. When you ride all day, the fatigue builds each successive day. If you push yourself hard, you'll end up getting frazzled and riding fewer hours each day. There are techniques for making this work.
