Roger, in response to training suggest long distance endurance cycling may prove beneficial i.e randonneur
brevet runs.
cheers

Hi Roger, you’ve picked a good bike, suggest 32-35 mm tyres that are rugged and are as flat proof as possible, the sides of Chinese paved roads often have fine wires from broken truck tyres that can cause frequent flats.
I used very fine merino wool (all most see through) jerseys from Patagonia which were cool, didn’t get heavy with sweat,protected skin from sun and kept me warm,and didn’t smell. you may want a light shell jacket and pants, a light synthetic insulated vest, some light fleece pull-over and pants, a light but sturdy two man tent enables you to store your bags inside with you at night and it should have open mesh and a good fly and extra tent pegs.
Hope this helps.

Can you offer me any advise on training prep, clothing for the extremes and camping?

I would appreciate any tips in this regard.

Regards Roger Hesford
