A journey of 5,070 miles begins with a single (roll, pedal?)…
Yeah, of course its possible. Here’s how to think about it. Look at the countries you would potentially pedal through, then look at
- Weather
- Road quality/access to services
- Political Situation
I would map a route based on the most favorable conditions of the top three.
Money, gear, etc. all depend on the above three factors. Answer yourself a basic question; what would happen if your bike got stolen or destroyed? Would you quit? Get a new bike sent to you? Buy a local village bike and keep going? How much money will you have in the bank?
Plenty online about biking across China. See what gear these riders take. In terms of documents, it all depends what countries you ride through.
Probably have to go North of the Black Sea as I imagine Iraq and Iran off limits, although biking through Istanbul, across Turkey, ferry across Caspian Sea, through the “Stans” and then into China seems easy enough (!!!).
You would need to carry all of your biking gear and parts after you leave Europe and head East (you could get spare parts send to you, or send them to yourself in advance). You could certainly bike through most of Europe and spend the night in Refugios/hostels but I imagine you’d want to camp most of the time. So lightweight tent, bivy sack, sleeping bag. My guess is you would need to carry at least 50-80 pounds of gear, you could consider a trailer too.
Access to food might be tough once you are east of the Caspian.
A lot of reasons not to do it, but if you have the mental and physical stamina and can deal with intense loneliness, daily setbacks of seemingly monumental proportions, why not? A lot would depend on your frustration tolerance and your ability to soldier on. A lot depends on circumstances completely out of your control…
