Training?
Answer: none required.
Just start with a flexible schedule for your first week.
It’s called On the Job Training.
130km the first day. Next 50. 12km, maybe.
Fourth day off.
After that it can settle down.
Do 200km a week bashing away for the months before you set off if you like.
Or, don’t bother.
In the scheme of things it doesn’t matter.
