Both before and during the trip we have been blantantly looking at other peoples travels for route ideas, comfort (especially when other cyclists take buses) and general entertainment. We have also met cyclists along the way whose blogs we are now also following.
Because this is a definately nerdy subcategory and mainly of use to us so we don't forget them, we have made a page with blog links that allows quick reference to whats coming up.
