depends on the tour.
if i'm in a national park zone, i'll ride every day, then stop at a national park for 2-3 days of hiking. that counts as a break from cycling. otherwise would plan riding every day city to city, with a 2-3 day stopover in a hotel/guesthouse and spend the days wandering thru the city.
if i'm on an extended tour thru isolated areas, i'll pick up some extra food, find a pleasant campsite, and spend a day reading.
