My wife and I are doing a 2+ month self supported tour of Eastern Europe starting next moth. We will start in Copenhagen, and have 6 countries we want to visit; but other than that we have only the first 4 days' route planned. However, with our track record that will likely change. A few years ago we were starting a 3 month tour in Lisbon, Portugal, and only had the first day, leaving the city, planned. That plan changed when we were buying ferry tickets, and the clerk showed us a better route.

We do put a little more effort into our annual 1-2 week tours with our daughters: "The Girl's Tour". They both have limited time off work, and we need to be a little more structured than normal. We also want them to have an enjoyable experience so they will do it again next year.

This was a windy answer to a short question. No, we don't put a lot of effort into planning our rides, even our recreational rides near home. However, we do plan enough to have a map and a rough idea of our intended route. With the new phones it is all but impossible to get lost for very long.
