If I understand you right, this will be a 100 mile ride to be completed in one day. If so, with no load you should be ok as long as there are no really steep hills. Plan on a long day.

The X-0 is a cross bike. It is not designed for loaded touring. But, as long as you don't mind pushing it up steep hills(no granny gears), it can be made to work. Just about anything can be *made* to work. The 7000 would be a better choice for loaded touring.
