the longest I have done on the speedmaster is 640 in a day. dozens of 3-500 milers and several 2000 and 3000 miles plus trips (more days). No break downs, used up some tires, and came pretty close to running completely out of gas a couple of times. Rain, heat, hail, road construction, its all good.
