Yes, it depends on the person and how they tour.
I tend to get up and ride all day, ending at a campground or motel where I shower and put on a set of camp clothes, usually lightweight pants and shirt.
Wash my riding clothes in the shower and allow to dry over night or the next day while wearing set number two. So, two sets of compact riding clothes and one set of camp clothes (plus cold/weather gear) can see me riding indefinately.
My camp clothes are only worn in the evening while just showered and relaxing so they stay good for days. Pretty good system for me.
