As you will have found looking at other posts on this forum and others, before you start on your 600 mile overseas tour, do a two day, one night tour from your home.
First is your overseas tour type is it:
Which ever variation, you want to replicate it in the UK first over a weekend.
You cycle from your home (or if you live in the middle of a city, get a train 30 miles out)
Cycle for 30 miles with all the gear you will be carrying
Go to a place where you will be spending the hight
Then cycle 30 miles home the next day
Make a note of what you have used, and what you have not, and what you should have had but did not.
Next weekend repeat to a different area/night stop
You will now have a lot less kit
First is your overseas tour type is it:
- A credit card tour, where you cycle by day and your gear get carried from hotel to hotel.
- Or would it be a B&B tour, where you carry a change of clothes and a toothbrush from B&B to B&B.
- Or a full on camping tour where you carry the sleeping bag, tent, stove and kitchen sink.
