1, the Sichuan-Tibet line rode more than 400,000 times last year. No longer some people, but many, many people go to Tibet by bike.

2. It's more convenient to stay and eat on the 3 18 national highway than before. You can learn all kinds of news and itineraries of 3 18 cycling, and there are already a dime a dozen online. A random search will bring out a lot. It's not as difficult as you think. There are tents, too. Riding on the Sichuan-Tibet line is now a very mature line. Food and shelter are not a problem at all.

Altitude sickness varies from person to person and most people can tolerate it. Of course, a few people who overreact can give up this ride and see if their bodies can adapt next time.

Times have changed. Things that used to be difficult are not so difficult now. When people's needs are not great, food and shelter are very easy to solve. Don't worry too much.
