Going on a cycling tour straddled with heavy luggage is a terrible idea. It will not only make it difficult for you to undertake the journey but will be an additional liability. Keep minimal and really necessary stuff with you and discard everything else.
The bike is the most important part of this exciting journey for obvious reasons and it is best that you acquaint yourself with the vehicle. Check everything to assure that it is functioning well and make sure you are comfortable with the bike before you hit the road.
Cycling tours are fun but they are also physically taxing so your own health is also crucial here. Make sure you are in the best health and take adequate nutrition. Most importantly all during the trip be sure to stay hydrated.
