A young colleague (about 21/22 years old I guess) told me today he is going to Japan in the spring, exploring the country on rented bikes. He last cycled a few years ago, now plays football and runs 5 miles with his uni club.
So I ask the logical questions: how many miles a day will you ride, are you training now, you know a rented bike is not the same as your own, will you be cycling in traffic ....
Answers: dunno, 60/70 miles, maybe, my pal's organizing it, don't have a bike, we will have long breaks between cities ...
Me: you will have very sore bits, trust me on this
