Schedule automatic rest stops
On the Route menu, click Route options.
On the Profile tab, under Automatic rest stops, select the Stop for check box.
In the Stop for box, type or select the number of minutes you'd like each rest stop to be, and then in the rightmost box, select the amount of time you'd like between rest stops.
Click OK.
Note If you have already created a route, MapPoint automatically changes the driving directions to include these new rest stops.
