It is a lifestyle that has always appealed to me. I am currently following our friends latest journey. They are a couple in their seventies who have traveled extensively by bike and then land rover. When they are not travelling they share their time between the UK and NZ. They have covered the whole of Europe including Russia. Before Covid halted their travels they had traveled from Alaska to Guatemala. They are currently travelling Overland to South Africa and at this moment are in Senegal. It is not a journey I would undertake but good luck to them.
I met a retired French couple in Colombia and their story is very interesting.
They started several years ago in Alaska having brought their Campervan over and they are driving to Ushuaia in approximately six month stages.
They have family at home, notably grandchildren, so the Summer season is spent in France with family and the winter season is spent exploring the Americas. They find a safe place to store the van while they "go home".
I thought it was a very creative solution to two very competing desires.
I will get a tour as I've brought the gear!
I hate to be "that guy" but having all the "gear" is no guarantee of achieving anything.
Indeed, acquiring the "right" gear is often used as a delaying tactic. "I'll go when I have X bike or Y tent or Z sleeping pad is quite common. Especially these days when we are bombarded by targeted material online.
I know people like that and have met many, many more.
There's another inspiring thread on here about someone heading off with a beach shelter for a tent. Now, that is a great attitude!
I've mentioned before a guy I know in NL who makes a tidy living selling "as new" touring bikes. Bought with great plans, at great expense but as things turned out, the equipment wasn't the barrier to going.
I'm pretty sure a regular look on second hand sites will show a steady stream of similar.
One of the problems is that these people are unrepresented on fora like this. (In fact, most people who ride bikes are unrepresented.) There are not many who will willingly volunteer that they have some kind of a block, nearly always a fear of some kind, that prevents them heading away. Even for a day.
To go off an a tangent and to give an idea of some of the fears that affect people, I met a guy once while I was away on my bike. Oh, how he'd love to do something like that! And then came the buts. The expensive gear. I told him my bike cost €200 (and I overpaid!) The big distances. My shortest day is about 5km. And so on. Eventually, in a very roundabout way he suggested that the real problem was being alone in the silence, especially at night. Not a fear of the dark, nor of monsters or murderers but being alone, without distractions, with himself. That shut me up.
We see and read of the people who want to do it and those that do it. Rarely those that nearly did it. Any forum like this sees a steady stream of newbies full of enthusiasm, acquiring bikes and then disappearing. Perhaps gone off on tour, but I think, in most cases, not.
Despite how it may appear, I understand your responsibilities.
However, I see nothing in your posts that demonstrates how you plan to manage them. There's nothing of the detail like in the tent/sleeping bag/cookset discussions. When the responsibilities are afforded the same research, discussion and especially, action, then you'll be off!
Properly organised you'll be able to relax and get the full value.
You won't hear me but I'll be cheering the loudest.
Good Luck.
