How many miles per day? Mountains or flatlands? Whats your goal(s)?
Frankly any plan will probably work. I’ve known people get off the couch and ride 500+ mile tours because they ride at a slow pace and not too far each day. Dragging a heavy loaded bike over multiple mountain passes each day is probably slightly different, but why not plug your tour into Plan Builder as a multi day event and choose the appropriate daily time and intensity you expect and see what it spits out.
