Any plan is better than no plan
For some of you, preparing for a bikepacking event is new. 3,000 km is a long way, so the more prepared you are the more enjoyable your trip will be. As the saying goes: Any plan is better than no plan.
Most people do around 3,000 km of training in the months leading up to their ride. However, you can get away with much less (virtually none) if you have a strong cycling background, simply by starting slowly and building your fitness up during the ride.
All the same, you should be comfortable riding at least several hours a day by the beginning of your tour.
You can download a simple training plan, written by Jeff Lyall, here (PDF) to get you started.
