What preparations should be made before riding in Sichuan and Tibet, and what problems should be paid attention to during the journey?

First of all, we should collect, consult and sort out all kinds of relevant data and information along the way, including newer versions of maps and traffic maps, as well as geographical, historical, cultural, historical and meteorological data along the way. Then make a detailed travel plan according to your own or team's physical condition, holiday length, travel season and other factors. Generally speaking, the best season for long-distance cycling travel is from May to 10 every year.

Long-distance riding is best to go hand in hand. I suggest you go to the next travel app to recruit teammates. Tours are very popular on the 3 18 line, and many riders ~ people in front are willing to share road conditions and sudden weather and events ~ ~ which is more practical; However, the number of long-distance travelers should not be too large, and the ideal number is 3 to 5, preferably with opposite sex counterparts. There are too many people, so it is difficult to get accommodation along the way, and it is difficult to receive in remote small places. Because of the differences in people's personalities and hobbies, it is difficult to act in unison when there are many people. The number of people is too small and the security is poor. And in case of special circumstances on the way, the number is too small to take care of each other. In addition, if the number of people is too small, everyone's relative burden will increase, and some materials and equipment, such as car repair tools and camping equipment, only need one copy.

Clothing: If you ride in summer or warmer seasons, you'd better buy a specially designed short riding suit. It has the functions of heat preservation, ventilation, wind protection and rain protection. There is also a leather pad in the cycling pants, which is wear-resistant and breathable. Can adapt to riding in various climatic conditions. Just more expensive. If you don't have cycling clothes, especially cycling pants, you can wear elastic tights directly, without wearing other clothes inside, and apply some grease to the parts that are often rubbed.

Wear a long-sleeved coat and a sun hat when cycling in summer to avoid sunburn. When riding in winter or in cold regions, besides keeping warm, we should also pay attention to prevent clothes, pants, shoes and socks from being too tight, which will lead to poor blood circulation and frostbite. In addition, you can't wear a mask when riding. If you wear a mask, the exhaled hot air will unconsciously form thin ice outside the mask, causing facial frostbite. The most vulnerable parts of frostbite in winter are ears, nose, hands and feet, so special attention should be paid to the insulation of these parts. The combination of cycling and cart walking can be used to promote and improve the blood circulation of the whole body. Also prepare a rain batch, which has many other uses besides rain protection.

Other equipment: In order to prevent wind and small flying insects from invading your eyes, you should be ready to ride glasses. Colored ones can protect against the sun, colorless ones are suitable for cloudy days, and light yellow ones are especially suitable for night. It is also essential to prepare a small medicine box. Long-term medication includes: drugs for treating diarrhea, gastrointestinal discomfort, cold, acclimatization, anti-inflammation, trauma, eye drops and so on. In summer, we should also prepare some ten drops of water, wind oil essence, cool oil, prickly heat powder and so on. Prepare some chilblain cream, "Cold Pain" and ginger tea in winter. If you are in the northwest, Xinjiang and other places, you should prepare more drinking water (5 to 10 liter per day)
