I have a trip I need to make. I have 4.5 days to make 2,800, round trip. About 10 hours in the saddle each day. All freeway driving. I have done 400 miles in a day before, but I am not sure how doing double that for 4 days in a row will work. At this point, I am not sure if I want to ride the bike, or spend the money and fly. Any thoughts from anyone who has made a trip like this?
