that's exactly what I did when I went to Serbia. I even went entirely against what Machka usually suggest - I never do really long rides, my longest ride until then was 130km to the sea. I'd never even camped before and guess what, I had a great time and my daily mileage went from 80km daily to 200km and once even 240km. I changed my planning on the fly as I saw fit and it all worked out great
